Analysis (NLPCA) on 34 demographic, housing, education and asset possession variables,
which categorises households according to their eligibility in the basis of a cutoff (Fabara,
2009). Almost all variables, but one, can be calculated directly from the LSMS, therefore,
I used the 2010 Population and Housing Census to complete the exercise (further detail in

Children Stunting in Ecuador
Note:
a) red line represents the -2 sd. threshold for underachievement
in height-for-age z-scores compared to the standard distribution of well-
nourished WHO sample. b) red line is the national mean stunting prevalence
(23,90%). Ages 1 and 2 show higher values than the mean, specifically, 31,6%
and 27,15%.
Descriptive statistics of the full LSMS sample show a 23,9% prevalence of children stunt-
ing, 19,9% in the urban areas and 32,8% in rural ones. Also, there is a stunting prevalence
above the population mean for children of ages 1 and 2 (Figure 2). Regarding the transfer,
from the total sample, 1’122.435 households receive BDH from all types (25,83% from total
