Administrative (pop. 2001: 1,033,977) and historic county, southern England. It adjoins London on that city's northern side; its county seat is
Hertford. It includes the two early "garden cities" — Letchworth (1903) and Welwyn Garden City (1920) — and four of the eight new towns planned around London since World War II (1939 – 45). With an array of direct road and rail links to London, it houses light industries, offices, film studios, and thousands of exurbanites.
