Demographic Mixed Bag – November 2019 Cambridge municipal election

I have been curious since the recent election whether there were any patterns in voter turnout that might be discerned when the information about who voted became available. That data became available recently and it’s kind of a mixed bag. There are still a lot more younger voters than there were before 2017, but not as many as in 2017. There was a modest increase in the youngest range (up to about age 26 – credit for that probably goes to the supporters of Burhan Azeem and Jivan Sobrinho-Wheeler), but the numbers actually disproportionately dropped for most age ranges from about 27 through the middle age years. Interestingly, the number of voters increased for those in the 70-80 range. We can all speculate about why those numbers would be up when overall turnout was down.

Overall the number of registered voters increased from 66,354 in 2017 to 68,839 in 2019 (including those with listed birthdates) – a 3.7% increase. The number of people who actually voted decreased 4.8% from 22,407 to 21,329. Voter turnout in 2017 was 33.8% of all registered voters. That dropped to 31.0% in 2019, but that’s still relatively high for a municipal election (it was 28.2% in 2015 and 25.2% in 2013).

Here are some graphics to illustrate this, starting with the distribution of voters by age (in 3-year intervals, 18-20, 21-23, etc.) in the Nov 2019 election.

Voted 2019

Compare this to the 2017 distribution – especially the peak at 27-29:

Voted 2017

Notice that in 2015 there were far fewer people in their 20s and 30s voting with a clear dominance in the 65-70 range.

Voted 2015

When we look at 2017 and 2019 side-by-side you can more easily how some age ranges saw significant decreases (more than the ~5% overall drop) and other age ranges actually saw increases.

Here’s an annotated graph highlighting some of the more interesting changes.
