This is a simple and regrettably incomplete time-series on the percentage of U.S. households with access to a computer, by year.
A data frame with 19 observations on the following 2 variables.
the estimated percentage of households with access to a computer
Various: U.S. Census Bureau, Current Population Survey, and American Community Survey
Data are spotty and regrettably this is not a perfect time-series. However, it is useful for an in-class exercise to show that the proliferation of household computers (over time) in the United States comes in part because of globalization. Use it for that purpose. The data are reasonably faithful, but don't treat it as gospel. Exact sourcing available upon request.
