Merged the block points into a national shapefile. Checked that all the block points reside within the correct block group polygons using a spatial overlay. As a result: 1 corrected latitude and longitude coordinate errors for features in Alaska, and 2 moved block points that were in the incorrect block group and updated the latitude and longitude values of the block points.

How do I obtain data? What are compound geographic levels? Can I just get a copy of every data table you have? How long does a data extract take?

Should I use 1-year, 3-year, or 5-year ACS data? Which ACS year range is best for comparisons with decennial censuses? Why do I receive so many data files in my downloaded zipped file? What do the field names e. What is wrong with the data? Something is wrong with the data I downloaded. What should I do? I downloaded some GIS files, but where are the census data?

Now how do I join them together? Why am I missing columns of data when I bring the. What projected coordinate system are the GIS files in? Why don't newer shapefiles align with older shapefiles? I have a suggestion for how you can improve your website!

Do you want to hear it? Back to Top. Aggregate data summarize sets of individuals through counts, sums, means or other aggregate statistics. The NHGIS specifically provides spatially aggregated census data : data summarizing individuals within particular areas, such as states or counties, where the "individuals" might be persons, housing units, farms, libraries, newspapers or any other features that were at some point counted in a U.

No individual-level records, with or without personally identifiable information, are included anywhere in the NHGIS. So if you are trying to find your great-great-great grandfather who homesteaded in the late s, you will not have any luck with NHGIS data. The original source of most of the aggregate data, with a few exceptions, is the U. For earlier censuses, NHGIS data are generally derived from secondary sources: separate projects which have, over the course of several decades, undertaken the arduous conversion of pre-computer-age historical data from print media to a digital, machine-readable form.

Most of this work was completed by Michael Haines, Donald Bogue, Andrew Beveridge and their respective research teams. Documentation for most sources is available on the Tabular Data Documentation page.

The primary guide for historical census tract boundaries was original census maps and, for early county boundaries, it was the book, Map Guide to the U. Back to Top NHGIS time series tables link together comparable statistics from multiple censuses in one table with standardized labels and codes for all years.

Users can view available time series tables and select and download them in various layouts through the Data Finder. Complete information on the derivation, layout, and coverage of time series tables is available here. In Census documentation, these categories are typically referred to as "iterations" or "components.

For example, Summary File 2 has two breakdown variables. Loading Close. Do Not Show Again Close. Sign In. Geographical Information Systems GIS A Geographic Information System GIS is a digital information system that allows users to create, manipulate, analyze, and display spatial or geographic data, along with their associated attribute data table s. Mapping GIS is a superb visual tool; it can also be used to create an unlimited assortment of hardcopy maps.

These standards and guidelines are developed when there are no acceptable industry standards or solutions for a particular government requirement.

Although FIPS are developed for use by the federal government, many in the private sector voluntarily use these standards. FIPS are not always mandatory for Federal agencies.

The applicability section of each FIPS details when the standard is applicable and mandatory. State agencies administering federal programs like unemployment insurance, student loans, Medicare, and Medicaid must comply with FISMA.

While FIPS is required for federal government users, the standards are valuable resources for non-government organizations looking to establish strong information security programs.
