# An "*****" entry in the margin of error column

This is a very interesting table note to an ACS table.

This table, of sex by age

https://data.census.gov/cedsci/table?t=Populations%20and%20People&g=0400000US36&d=ACS%205-Year%20Estimates%20Detailed%20Tables&tid=ACSDT5Y2018.B01001&hidePreview=true

has **** in the margin of error column, and this note of explanation

“An "*****" entry in the margin of error column indicates that the estimate is controlled. A statistical test for sampling variability is not appropriate.”

I’m not really sure what this means. Any help would be greatly appreciated!

Thanks

• Thanks all. I think this explains it, "Because the weights are designed in such a way that the certain margins (age, sex, et al) are fixed to independent estimates, usually from the population estimates program, the estimates from ACS are treated as if they do not have sampling error."
