VT Census Case Studies : ACS Benchmarking B25024 - Number of Units (ACREA)
Created and last modified by molfe on 04 Jan 2016
Notes:
- Bolded: ACS 90% MOE crosses 0 (no data still with MOE)
- Arlington County data is weighted by the number of units within the property.
- Not all properties have a units counts, which drives the number of housing units down (especially when the NA is for a multifamily).
- Number of unknown units count: 206 (2009), 233 (2010), 237 (2011), 248 (2012) and 463 (2013)
- Unknown are those properties that did not have a description on the type of property or number of units
- All prepared Arlington County data are used in the tabulations. When calculating census tract and block group (bg) comparisons, only those data that are within a designated tract/bg are included. When geocoding addresses along the county boarder, rooftop coordinates can occur outside the county. When merging tract to coordinates, these properties would not receive a tract/BG ID number
