Lead poisoning is commonly associated with children living in homes built before which year?

Explanation:
Lead-based paint was banned for residential use in 1978. Homes built before 1978 are more likely to contain lead paint or lead-containing dust, which can deteriorate and pose a risk to children who may swallow paint flakes or inhale dust. That regulatory cutoff date creates the strongest association between lead poisoning risk and housing age, so the correct year is 1978. The other years don’t identify the official threshold for the ban: 1980 and 1995 are after the ban, reducing the likelihood for new construction, while 1960 is also before 1978 but does not represent the specific regulatory cutoff commonly referenced.
