Abstract

In this study, we provide an assessment of data accuracy from the 2020 Census. We compare block-level population totals from a sample of 173 census blocks in California across three sources: (1) the 2020 Census, which has been infused with error to protect respondent confidentiality; (2) the California Neighborhoods Count, the first independent enumeration survey of census blocks; and (3) projections based on the 2010 Census and subsequent American Community Surveys. We find that, on average, total population counts provided by the U.S. Census Bureau at the block level for the 2020 Census are not biased in any consistent direction. However, subpopulation totals defined by age, race, and ethnicity are highly variable. Additionally, we find that inconsistencies across the three sources are amplified in large blocks defined in terms of land area or by total housing units, blocks in suburban areas, and blocks that lack broadband access.

评估2020年加州人口普查级别估计的准确性。

在本研究中，我们对2020年人口普查的数据准确性进行了评估。我们比较了加利福尼亚州173个人口普查区的样本中三个来源的街区人口总数:(1)2020年人口普查，为了保护被调查者的机密性，该普查中充满了错误;(2)加州社区统计，这是第一次对人口普查区进行的独立枚举调查;(3)基于2010年人口普查和随后的美国社区调查的预测。我们发现，平均而言，美国人口普查局在2020年人口普查中提供的街区总人口没有任何一致的偏差。然而，按年龄、种族和民族定义的亚人口总数变化很大。此外，我们发现，在按土地面积或总住房单位定义的大型街区、郊区街区和缺乏宽带接入的街区中，三种来源之间的不一致性被放大。

期刊介绍： Since its founding in 1964, the journal Demography has mirrored the vitality, diversity, high intellectual standard and wide impact of the field on which it reports. Demography presents the highest quality original research of scholars in a broad range of disciplines, including anthropology, biology, economics, geography, history, psychology, public health, sociology, and statistics. The journal encompasses a wide variety of methodological approaches to population research. Its geographic focus is global, with articles addressing demographic matters from around the planet. Its temporal scope is broad, as represented by research that explores demographic phenomena spanning the ages from the past to the present, and reaching toward the future. Authors whose work is published in Demography benefit from the wide audience of population scientists their research will reach. Also in 2011 Demography remains the most cited journal among population studies and demographic periodicals. Published bimonthly, Demography is the flagship journal of the Population Association of America, reaching the membership of one of the largest professional demographic associations in the world.
