a. Tubewell depth includes two categories: shallow wells and intermediate-depth well. b. Tubewell depth includes two categories: shallow wells and deep wells. For both cases, shallow wells are used as a reference.
The No. 1, 3 and 5 analyses are similar as the No. 2, 4 and 6 analyses, respectively, except that the education variable is replaced with the wealth variable.
