The main contents are key findings and messages regarding the relationship between contraceptive use and fertility, for 195 countries or areas of the world. These highlights will draw mainly from World Population Prospects 2019, and model-based estimates and projections of family planning indicators 2019. Policy-related implications of and responses to trends in family planning and fertility will be integrated throughout the text. In particular, these issues are of relevance for contextualizing Sustainable Development Goals 3.7.1. and 3.7.2. and the achievement of the 2030 Agenda.

This booklet is based on the Estimates and Projections of Family Planning Indicators 2019, which includes estimates at the global, regional and country level of contraceptive prevalence, unmet need for family planning and SDG indicator 3.7.1 "Proportion of women who have their need for family planning satisfied by modern methods".

The report presents findings from the 2018 revision of World Urbanization Prospects, which contains the latest estimates of the urban and rural populations or areas from 1950 to 2018 and projections to 2050, as well as estimates of population size from 1950 to 2018 and projections to 2030 for all urban agglomerations with 300,000 inhabitants or more in 2018. The world urban population is at an all-time high, and the share of urban dwellers, is projected to represent two thirds of the global population in 2050. Continued urbanization will bring new opportunities and challenges for sustainable development.

This is the fifth report in the series of publications which examine the prevalence of contraceptive use around the world. It contains data covering 160 countries, including 125 developing countries and 35 developed countries, representing 96 per cent of the world population. The review is based primarily on data obtained from nationally representative sample surveys, and includes two new chapters analysing contraceptive use dynamics and national policies relating to fertility, contraception and population growth.

First multi-year cumulation covers six years: 1965-70.

The population and housing census is part of an integrated national statistical system, which may include other censuses (for example, agriculture), surveys, registers and administrative files. It provides, at regular intervals, the benchmark for population count at national and local levels. For small geographical areas or sub-populations, it may represent the only source of information for certain social, demographic and economic characteristics. For many countries the census also provides a solid framework to develop sampling frames. This publication represents one of the pillars for data collection on the number and characteristics of the population of a country.
