The "Hard-To-Count" (HTC) maps are based on data from the US Census Bureau. An HTC score is a prediction based on a number of criteria that have been shown to make a tract more likely to be "hard-to-count." Such factors include foreign born parents, language isolation, income level, education level, and home renters versus home owners, among others. Tracts are shaded according to their “hard-to-count” score. The higher the HTC score, the darker the precinct tract. Below you will find three maps: New York State, Long Island and New York City. Click on each Senate district to see the HTC scores.
