Title: American Community Survey (ACS) 5-Year Estimates for Coastal Geographies
Short Name: AmericanCommunitySurvey_CoastalGeographies
Status: Completed
Publication Date: 2014
Abstract:

The American Community Survey (ACS) is an ongoing statistical survey that samples a small percentage of the population every year. These data have been apportioned to 13 coastal geographies, and contain detailed demographic, social, economic, and housing characteristics. They represent 5-year estimates derived from the ACS Block Group summary files. Detailed information on the ACS data can be found at the Census Bureau's American Community Survey website and in their researcher's guide entitled, "A Compass for Understanding and Using American Community Survey Data". Detailed information on the geographies the data are available for can be found here: https://coast.noaa.gov/data/digitalcoast/pdf/qrt-american-community-description.pdf

Purpose:

The purpose of the time series demographic statistics data files is to provide users with socio-demographic information such as population, age, structures, racial and ethnic composition, income contributions, and residential mobility in a format that facilitates comparisons across time and space.

Notes:

10860

Supplemental Information:

Many of the goals of those involved in coastal management and policy include finding the balance in the coexistence of natural ecosystems and human society, therefore a complete picture of the geographic patterns of human activity and its relationship to the coastal environment is needed.

Data Quality

Completeness Report:

All of the data reported in these data files met the QA specifications.

Conceptual Consistency:

Data estimated for counties and states compared well with data reported in the U.S. Census Bureau site. ACS data estimated in other STICS geographies of interest (ex. watershed) were compared against data estimated for the same geographies of interest when using Census 2010 estimates. The differences found were in the range of 2% difference.

Process Steps

Process Step 1

CC ID: 616002
Description:

The 2010 Census Block Group polygons were imported into a GIS system to assign these polygons to political, place-based management program boundaries, and watershed/other jurisdictions. Estimates were obtained through a GIS overlay operation of Census Block Groups with all boundaries or study areas of interest. Block Groups that fell partially in the areas of interest were prorated by area to be included in the estimates (block group area proration methodology). The ACS 2010-2014 demographic variables data of block groups were then merged with the 2010 block group file containing the proration factors, adjusted by the proration factors, and then summarized to the study areas of interest. The exception of this process is County and State level estimates which were obtained by summarizing the ACS 2010-2014 demographic variables by the existent appropriate geography code in the file associated to each Census Block Group data. For description of jurisdictions or geographies used in this dataset, refer to https://coast.noaa.gov/data/digitalcoast/pdf/qrt-american-community-description.pdf.

All data manipulation was done using the Statistical Analysis System (SAS) software. The data are kept as SAS files and exported out as comma separated delimited and Microsoft Excel format for users' accessibility.
