Hi All,
I work for an organization that uses a lot of Census data on children. One of the more valuable tables I've been able to find in the American Community Survey data has been one called "Children Characteristics" (this is table S0901). I would love to get information on children in every county in Illinois, but for some reason the ACS only provides estimates for about 45 out of Illinois' 102 counties. I've never been able to find a clear answer on why this is the case. Does anyone know why the ACS doesn't provide those estimates for every county, and what are some alternative data sources you use if you've run into the same issue?
