Notes: -Two clusters in the North-West/South-West region were not surveyed in 1991; so the total number of clusters surveyed was 350 for the two periods.
-The sample sizes for households and children under 3 years old reported in the table are weighted sample sizes; anthropometric measures were taken or were consistent for 1587 children in 1991 and 1923 children in 1998, resulting in a total weighted sample size of 3500 children for the two periods. The non-weighted total sample size was 3321 for children.
-Yaounde and Douala are the largest cities in Cameroon and were sampled separately from other regions and other cities and towns that can be considered as intermediate cities.
