In creating your map of renter housing, you used the 2010 Census Tract as your choice in the map selection menus. Now, let's say you want to track changes in housing over time by comparing two periods: 1940 and 2010. Select 1940 Census Tract and explore the data categories available in the menus below. You can use Social Explorer's "Side by side" view to look at the 1940 and 2010 results within the same screen, if you'd like (check out Social Explorer's Use Side by side and Swipe maps help page).

You will see differences between the 1940 and 2010 Censuses. These differences often result in poor data interoperability because some of the attribute data measure different variables from year to year, and some of the spatial data don't describe the same places in the same way. As discussed in lecture, for example, spatial data mapped at different resolutions (i.e., counties in one map, zip codes in another) are less interoperable than data reported at the same resolution.

Comparing the 1940 and 2010 data pertaining to housing, describe one difference in terms of attribute interoperability, and one difference in terms of spatial interoperability.
