We dropped two large pieces of data this week: breaking down Idaho’s rising supplemental property tax levy bill and Idaho’s increasing student enrollment.

So, let’s mash up these data sets a bit.

This first table looks at the 10 largest supplemental levies in Idaho, and where those districts rank in enrollment:

As these numbers show, there is little connection between local levies and enrollment. There are plenty of other variables that affect the size of a supplemental levy — including a district’s overall property value and, of course, a community’s willingness to pay.

But a supplemental levy is worth a lot more to some districts than it is to others. So let’s look at our top 10, and levy dollars per student:

As I wrote about the new supplemental levy numbers this week — and sought reactions from state leaders — equity was a constant refrain and a recurring concern.

In that context, consider this: Moscow’s supplemental levy is worth 14 times more per student than West Ada’s levy. That’s not a misprint.

A couple of footnotes:

• If you’re wondering about the four other districts that rank in the top 10 in enrollment, three collect a supplemental levy: Bonneville ($5.8 million); Twin Falls ($5 million) and Vallivue ($4.5 million). Jefferson County does not collect a supplemental levy.
• The future of Nampa’s supplemental levy is very much in doubt. By a scant, 11-vote margin, patrons rejected a two-year, $24.15 million proposal Tuesday. District officials are pondering their next move.
