The ASA, in partnership with the American Sociological Association (ASocA) and Population Association of America (PAA), filed an amicus brief October 29 for two lawsuits against the federal government over its inclusion of a citizenship question on the 2020 census. The brief cites the three societies’ “unique interest in ensuring the integrity of the data generated by the 2020 census” and a deep concern “that an uncertain and untested change to that census will imperil the accuracy, reliability, and utility of a core tool for their research and decision-making.”
