Union County is 105 square miles and, by the Census Bureau's 2025 estimate, 601,863 people, roughly 15.6 percent of them aged 65 or over. It is also two counties in one. The eastern half, running from Elizabeth and Hillside down through Linden and Rahway to the Arthur Kill, is dense, urban and largely flat. The western half climbs: the Watchung Mountains cross the northwestern corner, and the county's high ground, around 560 feet, is in Berkeley Heights, and the 1,945-acre Watchung Reservation spreads across Summit, Mountainside, Berkeley Heights, Scotch Plains and Springfield.
That split changes what home care looks like. A caregiver in a Bayway two-family house is working three flights up with no elevator. A caregiver in a Westfield or Summit colonial is managing a staircase, a basement laundry and a driveway that ices over. A caregiver in a Plainfield Victorian is doing both at once. This is why we do not sell one package.
