Dear NHGIS User, We're pleased to announce several major updates to the NHGIS data collection: New American Community Survey (ACS) data 2016 ACS 1-Year and 5-Year Summary Files New time series data (Release 8) Geographically standardized time series now include 1990 data (as well as 2000 and 2010) for 10 levels of 2010 census units, from states down to block groups The standardized 1990 and 2000 data are derived entirely from census block data to achieve a high level of accuracy The data include upper and lower bounds to indicate the uncertainty due to boundary changes Dozens of other additions and updates include new tables that use "single race/ethnicity" categories to enable direct comparisons of race data across time New GIS files 2016 boundary files: 85 shapefiles for levels ranging from the nation down to block groups Historical place point files depicting the locations of incorporated, unincorporated, and census-designated places from 1900 to 2015 New types of data Geographic crosswalks: relationship files bridging 1990 and 2000 blocks to 2010 blocks Environmental summaries: land cover, temperature, and precipitation for counties and census tracts Vital statistics: annual summaries of births and deaths for states and counties Currently available data span 1915-1941 Upcoming releases will extend the data to 2007 Faster processing of large table requests Our improved extract system processes some types of large data tables, such as nationwide census block tables, much faster If you have questions or suggestions about these or other NHGIS features, please contact us at nhgis@umn.edu. We'd love to hear from you! Regards, The IPUMS NHGIS Team  IPUMS NHGIS | University of Minnesota  Copyright © 2017 University of Minnesota, All rights reserved.
