Description

PROBBLK represents the predicted probability that a multiple-race part-black respondent in the 2000 census, the ACS or the PRCS would have reported only black or African American race if asked for a single race response. This predicted probability has been multiplied by 100 for PROBBLK; users must divide PROBBLK by 100 before using it.

For an explanation of how the predicted probability was calculated, see RACESING.

Single-race blacks have a value of 100 on PROBBLK; other single-race respondents have a value of 000. Biracial black/'other race' people also have a code of 100 on PROBBLK because of the bridging methodology explained in RACESING.

PROBBLK is a 3-digit numeric variable which represents the predicted probability that a multiple-race part-black respondent in the 2000 census, the ACS or the PRCS would have reported only black or African American race if asked for a single race response. PROBBLK has two implied decimals. For example, a PROBBLK value of 068 should be interpreted as 0.68. PROBBLK specific variable codes for missing, edited, or unidentified observations, observations not applicable (N/A), observations not in universe (NIU), top and bottom value coding, etc. are provided below if applicable by Census year (and data sample if specified).

PROBBLK Specific Variable Codes
000 = Other Single-race Respondents
100 = Single-race Black Respondents or Biracial Black/'Other race' Respondents

User Note: Biracial Black/'Other race' people are also coded as 100 because of the bridging methodology explained in RACESING. For an explanation of how the predicted probability was calculated see RACESING.
