Facts from the FBI and Department of Justice on blacks in America:

Black males commit 56% of all robbery, 53% of all murder, making up less than 7% of the US population, black males commit 1 in every 3 rapes, FBI Table 43

As of 2008, young black men kill at a rate of 7 times higher than white men. Homicide Trends in the United States, 1980-2008 Annual Rates for 2009 and 2010 pg 11

42% of all cop killers are black. Law Enforcement Officers Feloniously Killed Race and Sex of Known Offender, 2004–2013

Blacks victims of homicide are 93% of the time killed by other blacks. Black Victims of Violent Crime pg 3

In 2013, blacks made up nearly 38% of the total prison population, despite being only 13% of the general population. Jail Inmates at Midyear 2013 Statistical Tables

Black males have "mean testosterone levels 19% higher than in whites, and free testosterone levels were 21% higher". Higher levels of testosterone are linked to aggression. Serum testosterone levels in healthy young black and white men.

Testosterone linked to crimes of aggression, delinquency, substance abuse, also correlated with more violent crimes, parole board decisions against release and decisions against parole.

Some facts on the family dynamic and education achievement of blacks in America:

73% of black babies are born out of wedlock. National Vital Statistics Reports Births Final Data for 2010

In 2012, the mean critical reading SAT score for college accepted students was 428 for blacks and 527 for whites. For mathematics, it was 428 for blacks and 536 for whites. For writing it was 417 for blacks and 515 for whites. NationalCenter for Education Statistics

At both the grade 4 and grade 8 level, there is a persistent achievement gap between whites and blacks in both mathematics test scores and reading test scores in ALL states. How Black and White Students in Public Schools Perform on the National Assessment of Educational Progress

Some facts on intelligence levels of blacks:

Dickens and Flynn had to sidestep our citation of Shuey’s (1966) review of the literature, which shows that BlackWhite IQ differences in the United States have remained at 15 to 18 points, or 1.1 standard deviations, for nearly a century

The Totality of Available Evidence Shows the Race IQ Gap Still Remains

The study found that the average IQ for African Americans was lower than those for Latino, White, Asian, and Jewish Americans (85, 89, 103, 106, and 113, respectively; Herrnstein & Murray, 1994, pp. 273–278)

THIRTY YEARS OF RESEARCH ON RACE DIFFERENCES IN COGNITIVE ABILITY pg 236

Overall, 18% of Asians have an IQ over 120, 10% of whites do and only 1% of blacks. Nearly 84% of blacks have an IQ below 100, which is slightly below the average IQ for whites. The ratio of white Americans to black Americans who have an IQ over 125 is 30:1.

The IQ gap between blacks and whites in the United States—15-17 points—has not changed since it was first measured nearly a century ago. Both races’ test scores rose during the century, but the gap remained as large at the end of the century as at the beginning despite considerable social change.

Social Consequences of Group Differences in Cognitive Ability pg 24

For those who claim that IQ tests are biased against blacks and that's why they keep getting lower scores, there are IQ tests like the Raven's Progressive Matrices which don't have any language and rely entirely on visual pattern recognition. It's simply finding patterns in visual shapes. Even then there is a marked difference between black and white IQ scores, not only in America but internationally as well, like in Africa between white and black engineering students.

Harvard psychologists took a look at how black children adopted by well off upper-middle class white families at a very young age perform on IQ tests once they grow up in white families with good socioeconomic conditions. Black children adopted by white parents average 89 on IQ tests at age 17 (slightly better than the 85 average for blacks nationally). White children who grew up in the same households and had white biological parents on average scored Even with the same socioeconomic upbringing, the racial IQ gap remains.

The Minnesota Transracial Adoption Study, the largest and best-known transracial study, was designed specifically by Sandra Scarr and Richard Weinberg to separate genetic factors from rearing conditions as causal influences on the cognitive performance of Black children. It is also the only transracial adoption study that includes a longitudinal follow-up, with testing at ages 7 and 17 years. Scarr and Weinberg compared the IQ and academic achievement scores of Black, White, and mixed-race Black/White children adopted into upper-middle-class White families in Minnesota by adopting parents whose mean IQ was more than 1 standard deviation above the population mean of 100 (see Table 2). The biological children of these parents were also tested. pg 256 Subsequently, Jensen (1998b) discussed these studies at length and reviewed the evidence showing that age of adoption does not influence children’s IQ scores after age 7. pg 259

East Asian countries have on average the highest IQ scores. African countries have on average the lowest. European countries are generally between the Asian and African countries.

Race and IQ: A Theory-Based Review of the Research in Richard Nisbett’s Intelligence and How to Get It Abstract

Average IQ for a criminal in America is 85, right at the black average of 85

For those looking to pin the lower IQ scores of blacks on socioeconomic factors, IQ is largely genetically determined:

Some evidence suggests that heritability might increase to as much as 80% in later adulthood but then decline to about 60% after age 80.
