Fern Prairie resident Jim Fisher describes himself as the “old hermit of Skunk Hollow.” He has lived in his modest home on 1.5 acres since 1969. At age 68, Fisher could be the poster child for the rural community’s main demographic: older, well-rooted residents who live primarily on acreage.“I was looking for a place to rent,” Fisher said. “I immediately liked the wooded area around it and the creek that runs around it. A few years later, I entered into a contract to buy it.”Like the nation as a whole, Clark County residents are getting older as people live longer, postpone parenthood and have fewer children.The county’s median age increased from 34.2 in 2000 to 36.5 in 2010, according to the U.S. Census Bureau.Still, the county is relatively young compared with the national median of 37.2, and it still produces and attracts more children than the national average. Clark County’s younger-than-18 population grew 13.7 percent in the past ten years, compared with 2.6 percent nationwide.Part of the continued growth in the younger-than-18 population may be the attractiveness of the county’s schools and suburban lifestyle to families. But the county’s faith-based community also plays a role, community leaders said.Camas, La Center and Vancouver nearly match the county’s median age of 36.5. Battle Ground, Five Corners, Hazel Dell, Minnehaha, Orchards, Ridgefield, Washougal, Woodland and Yacolt come in below the county median. Above the county median are Amboy, Barberton, Brush Prairie, Cherry Grove, Dollars Corner, Duluth, Felida, Fern Prairie, Hockinson, Lake Shore, Lewisville, Meadow Glade, Mount Vista, Salmon Creek, Venersborg and Walnut Grove.
