Here’s a map we made with BatchGeo – it shows the first 250 rows of first- or second-generation immigrants in the data we had transcribed for Boulder. (In the data we had transcribed, there were just over 300 people who were born overseas or whose parents were born overseas, but BatchGeo only allows one to geocode 250 rows for free.)
The default view you see below shows the dots colored by mother tongue (yes, the 1920 census really contains “Jewish” as a mother tongue for a lot of people, at least in Colorado.) You can toggle what you want to color the dots by in the pull-down menu in the lower left-hand corner. And you can filter by just a particular value by clicking on that value. BatchGeo does show all the individuals in the data, even if they live in the same address. For example, if you click on that “Jewish” tag, you’ll see two families; if you click on the one a bit further north (Max Solomon) you can see that there are two cards under that, for Max and his wife Dora (to see Dora’s card, click on the arrow right on Max’s card.)
You can also view this map as a full screen map – that lets you see the spreadsheet information and gives you a somewhat bigger map.
For a really cool way to look at the data, drag the little street view guy onto the map close by some dots!

Since it’s so easy to toggle what we see, we can do some fun exploration with this map.
For example, we can color the dots by the different birthplaces of these people. When we do, we can see that there are people from lots of places: for example, Germany, Sweden, England, Illinois, Nebraska, etc. – and lots of people born in Colorado.
We can also filter the view with multiple variables. For instance, we can look at birthplace and then select Colorado, so now we only see the blue dots representing Colorado-born people. But we know that at least one of their parents must have been born elsewhere, since that’s how we selected the data (remember, only immigrants or children of immigrants in this selection.) So now we can re-color the dots by, say, father’s birthplace.
It was pretty common for people to have one immigrant and one native-born parent. For example, the dot on the corner of Pleasant and 10th is Hattie E Beckwith. She was born in Colorado, but her father was born in England and her mother was born in Maine.
