The problem

This post provides supplemental data for my research into early Utah education, 1870-1899. In it I explain how I made the age corrections to the legal school-age population for each state.

See the age corrections for every state at my web-page: http://www.troysrepublic.com/AgeCorrections.html

For eduction statistics, many statistics of interest are ratios of the school age population. However, it wasn’t until 1890 that the Reports to the Commissioner of Education (COE reports) reported the 5 to 18 population for each state and territory. In prior reports the school-age population was enumerated according to the legal school age for each state or territory. It could be 4 to 16, 5 to 21, 6 to 16, etc. Also, most of the age ranges are not inclusive, so 5 to 18 is really ages 5 up to but not including 18. So when I say, for example, that the legal school age is 5 to 17 what I mean is that the legal school age is 5 through 16. Also, the legal school age could change. For example, in 1875 Alabama’s legal school age was 5 to 21. In 1877 it was 7 to 21. Continue reading

Yes, I’m back after a long hiatus. I finally finished my Ph.D. (physics), so I hope I’ll be able to start blogging on a semi-regular basis. For the next few months I’ll be posting on education in 19th century Utah. Actually from 1870 to 1900. The data for this and upcoming posts came from the annual Report of the Commissioner of Education (abbr. COE). I’ve spent over a year collecting data and I’ve developed a method to “normalize” the data so that state by state comparisons are on a more similar scale. Owing to the fact that from state to state the legal school age differed, to make comparisons I needed to estimate the number of school age children between 5 and 18 for each state. For my age correction method see Age Corrections for Education Data for discussion and methodology.

Also, the end notes have a lot of information so you might want to check those out too. Continue reading
