The 2019 E-Stats provides estimates of e-commerce activity in key sectors of the U.S. economy for 2019, revises previously released estimates for 2018 and earlier, and places these estimates in historical context. Underlying data are collected in separate surveys of manufacturing, wholesale, service, and retail businesses. Data tables for each sector can be found at <www.census.gov/programs-surveys/e-stats/data/tables.html>.
