The data is public domain. The license tab makes it clear that you can use this data for any purpose, and you don’t have to credit or mention anyone.
The spreadsheet includes both 2017 & 2018 results. For the new questions this year, the 2017 answers are populated with Not Asked.
The postal code field was totally optional, and may be wildly unreliable. Folks asked to be able to put in small portions of their zip code, like the leading numbers.
Looks like I’m going to add one more thing to the to-do list for this week…
