MWITA-CC-2026-013 · Evidence A · P1
IBGE's 2022 Census release found couples with children were 42.0% of families, down from 56.4% in 2000; one-person domestic units reached 13.6 million, roughly one in five.
Counterevidence & uncertainty
Family and domestic-unit denominators differ; 2022 is a census reference point published later, and household composition alone does not reveal preferences or spending.
What would change the reading
Update with final weighting-area results and subsequent household surveys.
