Demographics & Economics
Demographic Data Unavailable for Area Code 845
County-level demographic data is not available for this area code because NPA boundary polygons are not publicly distributed by NANPA. We use geographic boundary data from the Colorado Open Data Portal to map area codes to counties, which currently covers 194 of 376 geographic area codes.
Demographic statistics (population, income, education, poverty) require county-level aggregations from Census ACS data. Without a county mapping, these aggregations cannot be computed. We are actively seeking additional data sources to improve coverage.
Statistics are population-weighted aggregations from Census ACS 5-year estimates where county boundary data is available.See Sources for details.
