Several names on this list are easy to mix up. Houghton Lake the CDP takes its name from
Houghton Lake the water body, Michigan’s largest inland lake, and its built-up area spreads
across three townships — Denton, Lake and Roscommon. It is a separate place from Houghton
Lake Heights and Houghton Point, two smaller unincorporated communities on the lake’s north
and east shores. The village of Roscommon itself sits inside Higgins Township, not Roscommon
Township, which is a larger, separately named block of land east of the lake.

Geography
Roscommon County covers 580 square miles, of which 520 square miles are land and 60 square
miles are water, close to 10 percent — among the highest water shares in the northern
Lower Peninsula. Houghton Lake, at roughly 22,000 acres, is Michigan’s largest inland lake
and dominates the county’s southeast corner; Higgins Lake, mostly in the county’s
northeast, ranks as one of the state’s clearest and second-largest. Much of the remaining
land sits inside the Au Sable State Forest, a state-managed pine and hardwood forest that covers
a large share of the county’s interior.
Crawford County lies to the north, Oscoda County to the northeast, Ogemaw County to the east,
Gladwin County to the southeast, Clare County to the southwest, Missaukee County to the west and
Kalkaska County to the northwest. Crawford County,
Oscoda County,
Ogemaw County,
Gladwin County,
Clare County,
Missaukee County and
Kalkaska County all border Roscommon
directly.
Demographics
Roscommon County had a population of 23,459 at the 2020 census, and the latest estimate puts
the county near 23,914 residents. The median age is 56.6 years, among the oldest in Michigan,
with 33.0 percent of residents 65 or older and only 14.2 percent under 18 — a profile typical
of a lakes-and-forest retirement and second-home county. Houghton Lake and St. Helen are the two
largest communities, together holding well over a third of the county’s population. Median
household income runs about $55,246 (2024 ACS, DataUSA), well below Michigan’s statewide
figure of $69,183 (2023 ACS). Population density works out to roughly 45 people per square mile
of land, low even by rural northern Michigan standards, and reflects how much of the county is
seasonal cottage property rather than year-round housing — the 2020 census counted 23,069
housing units against only 11,415 occupied households, a vacancy rate above 50 percent.
Economy & Local Life
Health care and social assistance employs the most workers in the county, about 1,270 people,
followed by retail trade at 1,232 and manufacturing at 879. Tourism drives much of that retail
and service employment: Houghton Lake’s shoreline carries marinas, bait and tackle shops and
boat dealerships built around the lake’s recreational fishing trade, and the community runs
three golf courses, including The Quest Golf Club, designed by PGA professional Ken Green. The
Houghton Lake Historic Village Museum preserves 14 restored buildings from the county’s
logging era, among them an 1876 hand-hewn log schoolhouse. The county’s biggest annual event
is Tip-Up Town USA, a winter festival held on Houghton Lake every January with an opening
assembly, the Polar Bear Plunge, ice-fishing contests and snowmobile races, closing with a parade
on the fourth weekend.
History
Michigan’s legislature formed the county in 1840 and originally named it Mikenauk County,
from an Ojibwe word for turtle. The legislature renamed it Roscommon County in 1843, after County
Roscommon in Ireland. Before it organized its own county government in 1875, the area was
administered in turn by Michilimackinac, Cheboygan and Midland counties. The village of Roscommon,
first settled around 1845, incorporated in 1882 and grew into the county’s seat of
government and largest year-round community.
Logging drove the county’s early economy: crews cut white pine across the Au Sable and
Muskegon River watersheds and floated the logs downstream to sawmills through the late 1800s.
When the pine ran out around the turn of the century, the local economy shifted toward the
recreational fishing and cottage trade that Houghton Lake and Higgins Lake still support today.
Three Michigan historical markers stand in the county, at Gerrish, the Pioneer House and the
Terney House.
