Central nervous system damage is the most serious effect of chronic lead poisoning because it can have long-lasting consequences on a child's cognitive function and overall development. Moderate anemia (Choice B), renal tubule damage (Choice C), and growth impairment (Choice D) can also occur due to lead poisoning, but they are not as severe or potentially irreversible as the damage to the central nervous system.

Rationale: The term 'vital statistics' specifically refers to the systematic study of vital events, including births, illnesses, marriages, divorces, separations, and deaths.

Morbidity refers to the prevalence of a specific illness or disease within a population, statistics is a more general term for numerical data analysis, and mortality specifically pertains to deaths within a population.
