VT Census Case Studies : ACS Benchmarking B25034 Year Structure Built (WMLS)
Created and last modified by molfe on 12 Nov 2015
Notes:
- Bolded: ACS 90% MOE crosses 0 (no data still with MOE)
- Where this ACS table includes all "Housing Units", WMLS only includes data on residential homes that sold on the market (e.g. no apartments)
- 2009 does not have available ACS data
