U.S. adults in their 20s and 30s plan to have fewer children than in the past
These declines in the number of children adults plan to have occurred almost entirely in the last decade.
In 2020, Pew Research Center launched a new project called the National Public Opinion Reference Survey (NPORS). NPORS is an annual, cross-sectional survey of U.S. adults. Respondents can answer either by paper or online, and they are selected using address-based sampling from the United States Postal Service’s computerized delivery sequence file.
