Notes:

Bolded: ACS 90% MOE crosses 0 (no data still with MOE)
Where this ACS table only includes "Owner Occupied Housing Units", the Arlington County data does not differentiate between owner or renter occupied. Thus, we are over estimating the county data depending on the number of residential housing units are renter occupied
5 year estimates are in constant 2013 dollars
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
