NHGIS

source

a handy way to get historic census data

source

this interface might be easier to use than the Census Bureau's

select your datasets, then wait for them to be generated

datasets are always for the entire US

there is generally less data for historic data (this is 1910)

source

dot density maps

if you want to follow along, try using this data

how?

you need polygons and a column of numeric data

tell QGIS how many points to make

sometimes this will be the value in the column itself

sometimes you will want to do some math (eg divide by 100)

keep in mind that you will have a new shapefile with the points you create

style in a way that works for the scale you're displaying at
