Description

RACBLK is a bivariate indicator of whether a person's race or races include black, African-American, negro, or mulatto, regardless of what additional race(s) the person reported, if any. Thus, RACBLK denotes the population of people who are "Black alone or in combination."

Beginning in 2000, individuals were allowed to report multiple races, so RACBLK and the other bivariate race indicators (RACASIAN, RACAMIND, RACOTHER, RACPACIS, and RACWHT) are not mutually exclusive in 2000 and later years. The number of reported races is given in RACNUM.

RACBLK is a 1-digit numeric variable.

1 = no
2 = yes

Comparability

This variable is only available in the 2000 census, 2010 census, the ACS and the PRCS. See RACE for detailed discussion of changes in the question beginning in 2000, when - for the first time - respondents could mark as many races as applied to them.
