Context The United States Census Bureau conducts regular surveys to assess education levels in the U.S. These surveys sample participants' highest levels of education (i.e. high school diploma, bachelor's degree, etc.) The attached CSV file aggregates data for the years 1995, 2005, and 2015. Content Data is organized into columns representing the survey year, age range, sex of participants, and education level. For example, [1995, 18_24, Male, ...] represents the 1995 survey for men ages 18-24. It's worth noting that the surveys varied somewhat in granularity. The 2015 survey divided categories more finely (18-24, 25-29, 29-34...) while the 2005 and 1995 surveys were coarser (18-24, 25-34, ...). This could create some distortion depending on the analysis used. Sources Main https://www.census.gov/topics/education/educational-attainment/data/tables.All.html 2015 Table 1.
