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…

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…
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…
Hello. I believe the data you're not finding are related to two data suppression issues in New York. More information and a list of affected geographies are available at https://www.census.gov/programs-surveys/acs/technical-documentation/errata.ht…
