This paper documents the construction and presents the main results of a poverty map of Mongolia based on the LSMS 2002/03 survey and the Census 2000. The methodology takes advantages of detailed information found in the survey and the exhaustive coverage of the census. It permits the calculation of poverty indicators at low levels of desegregation; aimag and soum in the case of Mongolia. The heterogeneity of the country in terms of poverty across aimag and soum should make the poverty map a useful statistical tool in any poverty alleviating programmes or projects. Our aimag-level results are also broken down by gender of household head.
