This issue of The Little Data Book on Gender reflects the structure of the World Development Report, 2012 on Gender Equality and Development. The report looked at the facts and trends surrounding the various dimensions of gender equality in the context of the development process. Whilst development has closed some gender gaps, other still persists, including excess deaths of girls and women, disparities in girls schooling, unequal access to economic opportunities and differences in voice within the household and in society. This handy pocket guide is a quick reference for users interested in gender statistics. It presents gender-disaggregated data for more than 200 countries in an easy country-by-country reference on demography, education, health, labour force, political participation and the Millennium Development Goals. Summary pages that cover regional and income group aggregates are also included in the book.
