Oh Where, Oh Where Have the Tax Credits Gone; Oh Where, Oh Where Could They Be?

This project turned out to be a bit of a departure from my original idea of measures of housing affordability in my previous post “It Hurts to Pay for Housing”. After familiarizing myself with SlippyMapper, I felt compelled to use it again.

I created this interactive map of affordable housing projects within the context of New York, NY from 2013 to 2016 utilizing LIHTC financing. I went through several late night attempts to use a csv database to create an interactive map where I did not have to input the data directly into the code. However, the csv reader would call every value under the field, leaving a mashing of text, numbers, and et cetera. Alternatively, I utilized Python’s dictionaries to get only the information I needed (and the information I didn’t) into the map.

The map itself is pretty straight forward, nothing fancy; just their locations, the project names and their allocation amounts on mouse over. The locations themselves and a little bit of info was all I needed to begin to suggest the premise of my argument. A standard briefing is offered subscripted in the title. Above is the output, below is the info source and code.
