Important message

This website is no longer maintained and will be closed in the second quarter of 2012. Instead, I am focusing my efforts on the International Education Statistics blog at huebler.blogspot.com. If you bookmarked pages on this site, please update your bookmarks. This site is mainly a mirror of articles posted on my blog. Links to the corresponding blog articles are at the bottom of most pages on this site. For example, a recent article on school attendance by grade and age in Liberia and the guide to integrating Stata and external text editors are also available on the blog. For additional information, please read "Website changes in 2012".
