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).

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.
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.
