Description

Descartes Labs is releasing mobility statistics (representing the distance a typical member of a given population moves in a day) at the US admin1 (state) and admin2 (county) level. A technical report describing the motivation behind this work with methodology and definitions is available here (pdf).

Usage

1
get_descartes_mobility(admin = c("county", "state", "all"))

Arguments

admin

character. One of county, state, or all.

From the methodology paper....

These statistics include the mean, median and quartiles. For the results reported here, we focus on the median of the max-distance mobility Mmax, which we designate m50. We further define a normalized mobility index m50_index = 100 * (m50 / m50_norm) where m50_norm is a "normal" value of m50 in a region, defined as the median m50 in that region during a designated earlier time period. We use the median weekday value of m50 between the dates of 2020-02-17 and 2020-03-07 as m50_norm to investigate COVID-19 related changes in the US. Note that m50 has dimensions of kilometers, while m50_index is dimensionless. m50_index is easily transformed to a percentage change from baseline behavior via m50_pct_change = m50_index - 100
