Local tick habitat

Westchester is 44% natural land cover (27% forest, plus open and brushy areas) across its 3.69 sq mi, home to about 16,094 people. That makes it the 66th-most wooded of the 119 towns in Cook County. Deer ticks live in wooded areas, along trail edges, and in tall grass: the more of that a town has, the more places ticks can quest.

Cook County reports about 2 Lyme cases per 100,000 people a year, the 0th-highest of 0 Midwest counties. That county-level disease pressure, combined with Westchester's local habitat, sets how high its daily score can climb when the weather and season allow.
