Interracial Breeding: White Women

March 12, 2010

UPDATE 03/31/10: New post on this subject- By the numbers: Interracial Mating in America


Curious about the general phenomenon of interracial couplings, I recently downloaded the CDC’s 2006 Natality Detail File to figure out just how much interracial matin’ goes on. For non-Hispanic white mothers who gave birth in 2006 (or at least 2,309,212 of them), the reported race of father looks like this.

Race of Father (white women):

Hispanic:                                             4.7%

NH White:                                          81.3%

Black:                                                    2.6%

NH Other:                                           1.7%

Unknown/Not Stated:                   9.7%

Couple of things that jump out at me:

  • WTF is other? Asians? Native Americans? Whoever they are they seem to be reasonably reproductively successful relative to other minorities..
  • Unknown? Are there that many women who don’t know who the daddy is?

While it would be easy to make the unknown category proportional with the rest of the data, I think it would be a mistake to assume that when a mother is so destitute as to be unable to name a father on the birth certificate, the dad will 90% of the time be of the same race. If we compare the mean educational attainment (in terms of years of schooling) of white females who breed with men of different groups, we see an interesting trend:

Race of Father Mean educational attainment Std. deviation
NH Other 14.93 10.073
Cuban 14.85 6.443
NH White 14.63 6.954
Black 13.47 7.515
Mexican 13.41 7.918
Unknown/Not Stated 13.31 10.790
All 14.45 7.531

This trend was not exclusive to whites. Mexican-origin and black mothers who were unsure of the father of their child, 12.9% and 36.6% respectively, had the least mean educational attainment of their respective groups. Similarly, for Mexican-origin and black mothers who had a father in the “Other” category the reverse was true. Black women with fathers in the “Other” category (n=2429) had a mean of 16.11 years of schooling, the highest of any non-Asian group I can find.

Only 55% of white mothers (n=1273706) live in states that collect data on which particular Asian nationality knocked them up.  From that data we find that white women with Chinese fathers (n=796) have a mean of 16.03 years of schooling, the highest of any particular white subgroup I can find. Following them closely are those with Asian Indian fathers (n=775) with a mean of 15.78 years of schooling. A significant portion of “Other” males appear to be Native American/Alaskan Indian (n=7584) vs. about 10000 or so total azns.

I would guess that overall for white women, the Other category is about 1/2-2/3 Asian while the “Unknown” category is disproportionately black and Hispanic. My puny laptop can’t handle any meaningful checks for bimodality, though a random sample of 5% of all responses showed very high variance in both of those groups.

Infant mortality and race

March 10, 2010

A while ago, Steve Sailer noticed that American Hispanics have lower infant mortality rates than American whites, who in turn have lower infant mortality rates than Blacks. Sailer later remarked that Hispanic mothers must “take good care of their health during pregnancy” to produce such results.

That seems very unlikely. Underclass Hispanic mothers are often poorly educated teens who, as I noted in my first post are among the least likely to utilize pre-natal healthcare. “Metabolic programming” and high obesity rates among US Hispanics indicate that pregnant Hispanic mothers don’t have the best diets, either.

Let’s take a look at the numbers, from the CDC:

Notice that relative to Chinese mothers, the Japanese mothers have high infant mortality rates.

Now compare US whites with Europeans:

Rank  ↓ Country or territory  ↓ Infant mortality rate
(deaths/1,000 live births)  ↓
Under-five mortality rate
(deaths/1,000 live births)  ↓
1 Iceland 2.9 3.9
2 Singapore 3.0 4.1
3 Japan 3.2 4.2
4 Sweden 3.2 4.0
5 Norway 3.3 4.4
6 Hong Kong 3.7 4.7
7 Finland 3.7 4.7
8 Czech Republic 3.8 4.8
9 Switzerland 4.1 5.1
10 South Korea 4.1 4.8
11 Belgium 4.2 5.3
12 France 4.2 5.2

Definitions of “infant mortality” vary by country, hence the much touted “Cuba has better healthcare than the US!”* is likely due to differences in reporting methods to a national health agency (or straight-up lies). Generally however, white Americans have much higher infant mortality than Europeans. 92% of whites and probably all Japanese-Americans have health insurance, so that shouldn’t be an issue. Or is it? From NPR:

As challenging as it is for young women to avoid pregnancy, for older women getting pregnant can be difficult. In fact, one out of every 100 babies born in the U.S. is conceived with medical help. And most of the time that means in vitro fertilization – IVF – where eggs and sperm are united in a Petri dish and then embryos are transferred to the woman.

One thing about IVF; it does increase the odds of multiple births. NPR’s Patti Neighmond reports on how some women feel about that and what doctors are doing about it.


NEIGHMOND: The priority in Finland then is to achieve pregnancy with only one embryo. Dr. Veleva and colleagues recently did a study where each patient produced an average of five healthy embryos. A single embryo was then transferred to the patient, the rest were frozen. If the patient didn’t get pregnant the next month, another embryo was thawed and transferred. If the patient still didn’t get pregnant, then the next month another single embryo was thawed and transferred. And so on for several months.

Veleva says in the end women undergoing this process were more likely to have babies than women who received multiple embryos in the first place.


NEIGHMOND: But here in the U.S. doctors say that may not work as well. For one thing, women in this country usually have to pay for IVF treatments on their own. Many just can’t afford multiple rounds of IVF. In Europe, national health insurance typically pays.

Here’s a horrifying logarithmic graph of infant mortality comparing twins versus singletons; the solid lines represent different age-cohorts of singletons and the stripped lines represent twins [From: Misra DP, Ananth CV. Infant mortality among singletons and twins in the United States during 2 decades: effects of maternal age. Pediatrics. 2002; 110(6):1163-8]:

The twinning rate is already higher for blacks (that could explain the racial discrepancy**) and privatized IVF treatments are raising the white rate (and probably Japanese rate). If I was a white demagogue, I would come to the conclusion that privatized healthcare is: “Genocide of White ‘Muricans”. Rahm-care sounds kinda retarded but if actually efforts were made to emulate an efficient British or Canadian NHS-type system, I fail to see how the average American would lose.

*According to the CIA World Factbook, Cuba is 34% black/mulatto. If Cuba’s infant mortality numbers are indeed true, US OB/GYNs should do everything to emulate to Cuban healthcare system.

**Of course, underclass black mothers also have very poor behaviors and diets, so that undoubtedly plays a large role as well.

Hispanic Crime

March 8, 2010

A debate over ‘spanic crime has paleoconservative “intellectuals” Ron Unz and Jason Richwine desperately trying to out tard each other.

Unz, whose spurious claim that Hispanics have a lower crime rate than whites stirred off the debate, relies on faulty data and a few mistruths (eg. pairwise comparisons of cities with significant Hispanic populations to cities with larger black populations). Richwine (and other bloggers at Alternative Right) uses data showing that U.S.-born Hispanics have higher incarceration rates than immigrant Hispanics* as evidence of an impending Hispanic crime wave and Hispanic acculturation to inner-city black norms. While it should be clear to anybody making blog posts about crime and immigration that when immigrant Hispanics face charges of drug trafficking, simple assault, robbery, they can expect to be deported. U.S.-born Hispanics facing similar charges can expect to spend a few years in jail. Richwine demagogically chooses to either ignore this point or is simply incapable of comprehending it on his own.

Unz’s data and conclusions are probably wrong but his discussion of the relatively low violent crime rates of nearly entirely-Hispanic cities is an interesting one. El Paso appears to have the 2nd lowest murder rate (2.8 per 100k) of any city with a population greater 500,000. El Paso is not an aberration. Other overwhelmingly (90+%) Hispanic cities along the Rio Grande have similar low numbers:

McAllen at 2.91 per 100k.

Brownsville at 2.26 per 100k.

While these cities are relatively safe compared to the black-influenced US national average (5.6 per 100k), they are relatively violent compared to the average white American murder rate of ~2 per 100k (according to Jared Taylor**). Reliable age- and poverty- adjusted numbers would be interesting to analyze. These cities have very high poverty rates and the average Hispanic Texan is around 26 years old.

La Griffe du Lion has claimed that Hispanics have fewer serial murderers, per-capita, than whites. Anybody who pays attention to violence just across the river finds that very hard to swallow….

I’ll have more on why majority Hispanic cities in the United States are much less violent than Mexican cities along the border and why the Hispanics in these cities seem relatively well-behaved compared to their co-ethnics in more diverse cities. Hint: Bowling.

*Studies have shown that U.S.-born Mexicans have worse health outcomes than their Foreign-born parents. The effects of the environment on crime would fit well with the general theme of this blog and I will get to get to some studies on that later (re: blacks and lead). But as I pointed out, Richwine is full of shit.

**Jared Taylor describes himself as a ‘white nationalist’ and it’s worth keeping in mind that nationwide Hispanic stats are skewed by the very criminally-inclined Dominicans and Puerto Ricans in the Northeast. That said, I’d trust his data more than I’d trust Richwine or Unz. Q: Are NY Puerto Ricans more violent than NY Blacks?

Gender differences and environmental inputs

March 6, 2010

In the comments section of my first post, commenter JB remarks

It is hard to fathom that well-to-do black women neglect to take doctor-recommended prenatal vitamins (which include magnesium). And that’s when vitamins are most important, no?

To which I reply:

I’d be willing to accept that genetic differences related to biochemical processing may also potentiate any environmental affects related to vitamin processing and blood-lead levels. Perhaps blacks simply have more difficulty utilizing vitamins and maintaining them in their bloodstream or removing toxins like lead for that matter?

My overall premise is that: Different groups may be more sensitive to certain environmental inputs than others.

While sex differences are more pronounced than racial differences, below I show a study on the effects of “social stressors” on pubertal and adult mice. Female mice exposed to pubertal or adult stress show significantly more sensitivity to amphetamines and nicotine, while males did not:

The present findings indicate that chronic social stressors alter HPA stress responses and locomotor responses to psychostimulants in females, and not in males, depending upon the age at which the animals underwent the social stressors procedure: Females stressed in adolescence showed enhanced behavioral sensitivity amphetamine, and females stressed in adulthood showed heightened corticosterone release in response to a new stressor.

[McCormick CM, Robarts D, Kopeikina K, et al. Long-lasting, sex- and age-specific effects of social stressors on corticosterone responses to restraint and on locomotor responses to psychostimulants in rats. Horm Behav. 2005;48:64-74.]

Human studies also show females are very negatively affected by stress in ways that males are not. This has societal implications as females will very soon outnumber males among medical school matriculates.

In contrast, prenatal exposure to nicotine appears to affect the blood pressure of male mice, but not female mice:

Prenatal nicotine had no effect on baseline BP but significantly increased Ang II–stimulated BP in male but not female offspring. The baroreflex sensitivity was significantly decreased in both male and female offspring. Prenatal nicotine significantly increased arterial media thickness in male but not female offspring. In male offspring, nicotine exposure significantly increased Ang II–induced contractions of aortas and mesenteric arteries. These responses were not affected by inhibition of endothelial NO synthase activity.

Carrillo’s way

March 6, 2010

In spite of receiving substantial media attention, there were very few surprises in the March 2nd Texas primaries. A Muslim-American who doubts the official narrative about 9/11 lost in the Democratic gubernatorial primary to popular Houston mayor Bill White. Gov. Good Hair handily defeated his two opponents, Senator Kay Bailey Hutchinson and Debra Medina, another candidate who thinks the Jews did WTC. All-in-all it would appear the primaries were much ado about nothing.

One GOP incumbent in a notable race did lose on Election Day however, and he lost in a landslide.

Victor Carrillo, a geophysicist on the Texas Railroad Commission was handily defeated 61-39 by a small-town accountant by the name of David Porter. Carrillo who, outspent his opponent 12:1, had the backing of all mainstream party leaders, held superior qualifications and relevant experience, was somewhat bitter about his loss:

Early polling showed that the typical GOP primary voter has very little info about the position of Railroad Commissioner, what we do, or who my opponent or I were. Given the choice between “Porter” and “Carrillo” — unfortunately, the Hispanic-surname was a serious setback from which I could never recover although I did all in my power to overcome this built-in bias.

I saw it last time but was able to win because the “non-Carrillo” vote was spread among three Anglo GOP primary opponents instead of just one. Also, the political dynamics have changed some since 2004.

Unfortunately, Carrillo’s well-reasoned argument is sandwiched in between his whining about personal tragedies. While it’s hard to feel sorry for someone who will likely spend the rest of their days earning six-figures as an oil industry lobbyist, he may of a point. From LatinaLista:

Curious to see if other Latino GOP politicians suffered the same fate, a quick scan of the 2010 Republican Party Primary Election Night Returns reveals that in every race on election day where a Latino or Latino-sounding name and an Anglo were running against one another, the Anglo won.

In fact, the Anglo won by a landslide

Perhaps the time has come where Hispanic GOP politicians need to start adapting more “American” names. LatinaLista notes the dynamic appears to be different in 3 and 4 way races.

In the race for Texas’ 17th Congressional district, Bill Flores (seen above) was able muster enough votes to get to a runoff election, yet he appears to face similar issues as Carrillo. While he had the backing of the NRCC and out-raised his closest opponent 3:1, he barely held a 4% edge over his soon to be runoff opponent 33:29. Apparently, a substantial portion of Waco voters seem to think he is an illegal.

It wasn’t all ray-sism that contributed to Carrillo loss. As noted about, the Teabagger impact on the election was not significant but still measurable. In statewide results it appears that as many as a third of voters were voting down-the-line against incumbents when they had opponents. Even Porter himself is a Teabagger:

Porter is running on an anti-Washington, D.C., anti-President Barack Obama platform of less regulation. According his Web site, Porter wants to use his position on the Railroad Commission of Texas as a “bully pulpit” to combat the “economic war [declared] by the current administration on the Texas oil and gas industry.”


Texas has real problems ahead. Days like these you almost yearn for the MBA governor. (joke)

Arrogant Indians; Uppity Blacks

March 5, 2010

3rd post in and I already need to invoke PlanetGrok’s law of HBD blogs. I went to a substantially African-American high school and I know of blacks all around the economic spectrum, so talking about blacks doesn’t really seem so absurd to be me. Yet, I realize a majority of blogs that focus on group differences (so-called HBD) have more malicious intents.  I do not. Still, this is a No-PC zone and while I realize a majority of blacks and Indians are decent people to be around (a majority of both groups are not ‘arrogant’), personal observations should still be talked about.

In a Steve Sailer comment thread I participated in, I noticed several other commenters remark on how ‘arrogant’ Indians in the West behave. PG has noted the narcissism of certain South Asian groups. Even Sasha Baron Cohen has a hilarious Indian-accented schtick based on this in the Madagascar movie series. A notable quote:

Excuse me, this is first class, its nothing personal, it’s just that we’re better than you

I had previously felt that my personal experience with Indian arrogance had been due to their understandable distain of me for my bad habit of dating their women. Now, I’m getting the feeling that this could be a characteristic of a measurable minority of Indians in the West. Many people do not notice this behavior from East Asians who often come across as humble, even if they feel differently in private.

As commenters in the Sailer thread noted: India is a craphole. While the 10 million or so ultra-selected Indians in 1st world countries are relatively successful, a majority of the 1.5 billion South Asians in the world live mired in poverty comparable to that of the average African. Lynn gives India an average IQ of 81 (their tested score was 79) and the surrounding South Asian countries IQs of 80 or below. Long-existent Indian diaspora communities in the Caribbean and Southeast Pacific are hardly impressive.

So what is there for Indians to be arrogant about? Similar behavior has also been seen from some upper-class professional blacks; redneck southerners even have a term for it: uppity.

I think an HBD explanation exists for this behavior. According to Jason Richwine, the average Indian-American IQ is 112. This is more than two-standard deviations above their national mean. Similarly, it takes an IQ of 110 or so to pass calculus, something only a small percentage of blacks would be able to do. My theory: given that most racial groups spend their formative years around each other, successful blacks and Indians are well-aware of their intellectual superiority over their co-ethnics. This may lead them to assume they are also vastly mentally superior to members of other groups. Presently, differences in average intelligence exist between groups, whether or not they are heavily genetic remains to be seen.

It will be interesting to see the developmental trajectory of India though. International investors are under the impression that India is the next China. Many of them went to the orient 20 years ago and saw a desperately impoverished Chinese state. They expect similar progress from India, they may be disappointed.

Group differences in substance abuse and environments

March 4, 2010

It has been noted that certain groups are more prone to substance abuse than others. Why is this?

Inherent differences in IQ may be a contributing factor, as may environmental differences. A few studies on rats attempt to provide answers:

Rats with different behavioral histories, defined by rearing and housing in either an enriched condition (EC) or an isolation condition (IC), were trained in a two-lever operant procedure to discriminate 5.0 mg/kg cocaine from saline. In cocaine dose-generalization tests, the IC rats exhibited an ED50 (1.01 mg/kg) significantly lower than the EC rats (ED50:1.55 mg/kg). The cocaine-appropriate responding was emitted when the rats were treated with d-amphetamine, and for the d-amphetamine test doses the ED50 (0.19 mg/kg) was again significantly lower for the IC rats compared to the ECs (ED50:0.33 mg/kg). These data suggest that IC rats are more sensitive to the stimulus properties of indirect dopaminergic agonists than EC rats and highlight the importance of environmental variables in governing an organism’s response to the stimulus properties of abused drugs.

[Fowler, SC, Johnson, JS, Kallman MJ. In a drug discrimination procedure isolation-reared rats generalize to lower doses of cocaine and amphetamine than rats reared in an enriched environment. Psychopharmacology 1993;110:115-8.]

If only my parents had beat me, maybe the Adderall would last longer.

A Chinese study also drew the same conclusions with an opiate (EE-Enriched Environment; SE-Standard Environment):

We examined whether manipulations of the enriched environment affected behavioral response to morphine-induced reward in adulthood. Male mice were exposed to the EE, or SE condition for 2 months. When they reached adulthood, we examined their locomotor responses to an acute and repeated injection of morphine. The increase of locomotor activity observed in the EE mice was significantly less pronounced than that in the SE mice treated with morphine at 10 mg/kg. These animals then received six additional daily injections of morphine, and the ability of these treatments to produce behavioral sensitization was assessed by a challenge injection of morphine (10 mg/kg) following a 5-day drug-free interval. Mice exposed to the EE condition showed a significantly less robust behavioral response to the drug-induced reward than the SE mice did. We conclude that early EE condition affected the ability of morphine to induce behavioral sensitization. The rewarding and reinforcing effects of drugs were further studied in the place preference paradigm. The procedure has been found to be sensitive to the rewarding effects of drugs. We observed in experiments that morphine at the dose of 5 mg/kg induced place conditioning in mice. This dose has been previously shown to induce intense rewarding effects in conditioned place preference, which does not increase when using higher doses of morphine (Zachariou et al., 2001). Interestingly, the dose of morphine (5 mg/kg) that established robust place preferences in SE mice failed to establish place preferences in EE mice. Thus, the EE mice are less sensitive to the reinforcing effects of morphine and showed less prolonged morphine conditioning.

[Xu Z, Hou B, Gao Y, et al. Effects of enriched environment on morphine-induced reward in mice. Exp Neurol. 2007 ;204:714-9.]

How significant were these differences? Here’s how much time individual rats from the different environmental groups spent in the “morphine-conditioned” box:
