Housing Age Profile
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Tilly, the median build year of 1983 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
A significant portion of Tilly's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

Lead Exposure Risk for Children in Tilly
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
When older housing represents 49% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Tilly address.
