ACS Data Users Group

Hello everyone!

I am new to this forum, but does anyone know whether there is population data by age by race at block group level in 2021 5-year ACS? I am now looking for the population in each age group and race at the block group level in California. For example, the While-alone population in the age group of 65+ in a block group.

Thank you very much!

The age by sex detail tables are in the B01001 A-G but the race tables only go down to the census tract level. B01001 does go down to the block group level but it is the overall (all races) table. So if you want AGE x SEX x RACE at the block group level you are out of luck. I looked at the decennial census "P" tables but there aren't age x sex x race breakdowns like the 5 year ACS tables.

PL94 has population and race at every level and age 18 only for age for 2020. If we ever get SF1 it would have age detail by single year, if any of that helps. I’m not sure how 5 year averages could help you when one of those years is a 100% count (a Census year, albeit a troubled one)

Absolutely, if I can get the 2020 census data like the P12 tables in Summary 1 Files in 2010, that would be great. I guess I have to wait for the 2020 data to be released.

Thank you for replying. In 2010 census, the P 12 tables have Age by Sex for each race at block group level. For ACS 5-year survey, as you said, it only goes down to Census Tract level. Maybe I have to wait for the 2020 census data to be released.

This info should be available in the 2020 Census DHC (Demographic & Housing Characteristics File) due for release this coming May. The DHC will be similar to Summary File 1 from previous censuses, with several changes that will mainly be reductions in geographic detail and subject coverage. More info is available here.

Thank you for the information!

I know it has been awhile - but were you ever able to find these in ACS? I am looking for age x sex x race at the census tract level and can't seem to find it.

Thank you!

Hi Louisa,

Age by Sex by Race at the census tract level for 2021 ACS 5-year estimates are available in Tables B01001A-G (with ethnicity available B01001H - I). Here is an example table:

https://data.census.gov/table/ACSDT5Y2021.B01001A?q=b0100*&g=1400000US11001000101,11001000201,11001000202

Is this what you are looking for?

yes, wonderful; thank you!
