In this paper, we discuss the suitability of smartphone data for quantifying movement and social contact. We show that these data cover broad sections of the US population and exhibit movement patterns similar to conventional survey data. We develop and make publicly available a location exposure index that summarizes county-to-county movements and a device exposure index that quantifies social contact within venues. We use these indices to document how pandemic-induced reductions in activity vary across people and places."^^; "2020-07-09"; "2020-09-03T16:19:27.374121858+00:00"^^; "https://doi.org/10.21034/iwp.35"; ; "https://creativecommons.org/licenses/by-nc/4.0/"; "2020-09-03T16:19:27.395381728+00:00"^^; "https://creativecommons.org/licenses/by-nc/4.0/"; "Research Paper"; "314", "190", "293", "846", "159"; "Institute working paper (Federal Reserve Bank of Minneapolis.
