Currently, the data module does not read in the LTDB 2010 census data set (population), and solely rely on the sample-based ACS data. Is this an intended behavior?

I understand the ACS data set covers all the variables in the 2010 census. But it should be preferable to use the population data compared to the sample data from ACS. This is also suggested in the comments:

read in Brown's LTDB data, both the sample and fullcount files for each year population, housing units & occupied housing units appear in both "sample" and "fullcount" files-- currently drop sample and keep fullcount

it was intentional for the sake of consistency (i.e. to keep everything from a single dataset when possible). In 2010, the fullcount variables are a subset of what's available fromt the sample variables, so i thought it was preferable to keep everything from a single source. This isn't the case in prior decades where the datasets have unique variable sets excet for population

i dont have a strong opinion about this, so if you think it's definitely better to use the fullcount instead, feel free to change it

I am not sure about the difference between 2010 sample and fullcount data (maybe you have confirmed that there is not much difference).

If only the ACS data set is used for 2010, it might be important to point it out in the documentation because users are relying on it to know what data they are exploring.
