Jefferson County is like a state within a state due to its size and diversity, with 7 cities, 5 towns and 17 unincorporated communities. Population is growing in some areas and stagnating in others, but overall, it is burgeoning. How do we address these shifting needs? The Jeffco League of Women Voters begins a four-part series in December to update Jeffco’s changing demographics and its ramifications. The LWV will present an overview at six unit meetings Dec. 13-15, with future focus on aging, housing and education. All are welcome. The Mountain Parks Unit meets at 9:15 a.m. Tuesday, Dec. 13, at Highland Rescue Team Ambulance District, 317 S. Lookout Mountain Rd., Golden 80401. Call 303-674-1780 for information. An evening meeting also is available; call 303-972-4238.
