A population of 757,837, a 40% non-Hispanic-white share, and a median household income of $90,923 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 8 and Congressional District 41.
The congressional districts whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
Twin score (0–100) = weighted cosine between tier-standardized fingerprints: presidential margins 2000–2024 with 12-yr trend and elasticity, ACS income, age, education, population and race, top reported ancestries, and religious adherence — chips name the closest-shared dimensions and the widest gap.
