Geography Awareness Week, GIS Day, and the 2020 U.S. Census

In raising-public-awareness news, the third week of November is Geography Awareness Week, and since 1999 the Wednesday of that week is GIS Day.

For this year’s GIS Day, the Library of Congress is holding a virtual event focusing on the 2020 Census, featuring a keynote by Census Bureau geography chief Deirdre Bishop as well as three technical papers. The program will be (or was, depending on when you read this) streamed on the Library of Congress’s website and on their YouTube channel on Wednesday, 17 November 2021 at 1 p.m. EST, and will be available for later viewing.

The Washington Post Examines Proposed Congressional District Maps

Redistricting—and gerrymandering—is one of the blacker cartographic arts. With the release of data from the 2020 U.S. Census, and the changes in state congressional delegations—some states gain a seat or two, some states lose a seat, others are unchanged—new congressional maps are being drawn up for the 2022 elections. The Washington Post takes a look at proposed congressional district maps in Colorado, Indiana and Oregon, and what their impact may be.

A Map of Hard to Count Communities for the 2020 U.S. Census

The HTC 2020 map is an interactive map of hard-to-count communities built for campaigns to increase participation in the United States’s 2020 census. Hard-to-count communities are populations that historically have a poor self-response rate: they return their census forms online or by mail at lower rates, requiring followup interviews by enumerators. The map shows response rates by census tract, and notes the demographics of each tract in terms of why the response rates might be low: lack of Internet access, or large numbers of people who are historically undercounted (poor, rural, people of colour).

Mapping Canadian Census Data

Statistics Canada released population and dwelling data from the 2016 Census yesterday. MountainMath’s CensusMapper project already has interactive maps based on that data: population change since 2011 (absolute and percentage), population density, and unoccupied dwellings—with presumably more to come, since the interface allows you to make your own census-derived maps.

Census Dotmap


Brandon Martin-Anderson’s Census Dotmap plots every person counted in the 2010 Census as a single dot on the map. Which is to say that there are 308,450,225 dots on the map. Zoom in and see (though it’s not labelled and can be confusing to navigate at higher zooms). I suppose this is the demographic equivalent of the 1:1 map of Borges’s “On Exactitude in Science.” Via Boing Boing.
