Letters in () indicate the key dimension(s) of poverty reflected by the census variable. E = economic, H = human, PR = protective (the others are political and sociocultural). Entries in bold indicate loadings > 0.444. Goodness of fit of the model testing the null hypothesis of no difference between observed data and an hypothesized seven factor solution, χ2 = 56.57, df = 48; p-value 0.186.
