I am looking at table B19013 for Median Household Income in a particular CBG (Block Group 4, Census Tract 42, Tulare County, California) and the 2021 5 year estimate is missing. It was present in the 2019 5 year estimate table, however. The guide to data…
We have noticed there are quite a few -666666666 values in the 2018-2022 5-year ACS estimates. These are for variables that have always had values previously. For example, B19067_001 (cash public assistance income). Out of the 31,895 CDPs we are interested…
Two questions from reading up on ACS data suppression (https://www.census.gov/programs-surveys/acs/technical-documentation/data-suppression.html) as background for understanding why there might be missing estimates (-666666666) at the block group level…
I usually look at measures by county, I run all the counties and see what percent have data (not -666666 etc.) If its less than 60 or 70% I have to see what other related measures are and what their percentage of valid numbers is. It would be great if…

Careful — a lot of data suppression as you’ll see if you try adding up nationally or by state — more outmoves than inmoves meaning a lot of inmoves are unaccounted for. Cells less than 10 suppressed is the apparent reason, you can make some dent by estimating…
Can we belabor the missing tracts for a moment? Reason 2? When you say no HHs in the tract do you mean samples? For special tabs and in some of the early ACS disclosure literature the Bureau uses the phrasing, "3 or more cases are required to publish…
It's common for data to be suppressed when there isn't a sufficient sample size. The suppression takes place to protect information about the respondents in those areas and to limit unreliable statistics. In many cases there are limited numbers of…
Try the C23002 race series (with letters A-I at the end). Some data for smaller populations could be suppressed. Here's the link for C23002B (Black -- each zip had data) - I don't use the A race letter for White as prefer non-Hispanic White under letter…
