Housing Age Profile
Cumberland Gap's housing spans eras before and after 1986; its median build year is 1994.

Lead Exposure Risk for Children in Cumberland Gap
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.
