How do we calculate my vote power?

What goes into the rating: Representation: how much weight one vote carries here compared with a statewide vote — the smaller the district, the more each vote counts. Decisiveness: how likely this race is to be close, based on past results or current analyst ratings, plus the number of candidates.

Representation: Above average · 61 out of 100

This district is a good deal smaller than its state, so each vote here carries more weight than a vote in a statewide race. About 582,270 people live here.

Show the representation math

score = 50 + 50 × ln(state population ÷ this district's) ÷ ln(50,000) = 50 + 50 × ln(7,044,056 ÷ 582,270) ÷ ln(50,000) = 61.52, measured against a statewide vote in MA (grades: 66+ high, 55+ above average, 33+ average, otherwise low; a statewide race is the 50 baseline)
