Subnational ideology and presidential vote estimates (v2022)

We provide new estimates of the ideological preferences and presidential voting behavior of Americans at the local level. We combine estimates of the ideology of about one million Americans based on 18 large-scale surveys between 2006-2021 with recent advances in opinion estimation to estimate the preferences of zipcode tabulation areas, states, counties, cities, subcounty units, school districts, congressional districts, and state legislative districts. We also aggregate presidential voting behavior to the level of these geographic units. These new estimates enable scholars to examine representation at a variety of geographic levels.

本数据集提供美国民众地方层面意识形态偏好与总统选举投票行为的全新估算成果。我们依托2006年至2021年间的18项大规模调查所获取的约100万美国民众意识形态估算数据，并结合民意估算领域的最新研究进展，对邮政编码统计区域（zip code tabulation areas）、各州、各县、各城市、县以下单元、学区、国会选区及州立法选区的民众偏好开展估算。此外，我们还将总统选举投票行为数据聚合至上述各类地理单元的层级。这些全新的估算结果能够为学者在多种地理层级上开展政治代表状况相关研究提供有力支撑。
