The US Census has a neat online tool that lets you get the census tract and block group codes for up to 10,000 addresses: https://geocoding.geo.census.gov/geo...ressbatch?form
However, I have 1 million addresses and don't want to do this by hand 100 times. Is there an alternative (free or cheap)? If not, is there a way to automate a somewhat complex data retrieval command in Stata 15.1? It would have to go to the website, click to add a file, and then click to get results.
Thanks.
