<p><strong>Disaggregation:</strong></p>
<p>Age, education, number of living children, marital status, socioeconomic status, geographic location and other categories, depending on the data source and number of observations.</p>

<p>The Population Division maintains an online database of empirical demographic data and selected tabulations (including fertility rates) from different sources including estimates produced by National Statistical Offices and regional statistical units. Data since the last round of SDG reporting are continuously updated from various sources: DemoData: Data Browser (online database of empirical demographic data and selected tabulations)<em>. </em><a href="https://popdiv.dfs.un.org/demodata/web/&quot; \l &quot;!#%2Fhome">https://popdiv.dfs.un.org/demodata/web/#!#%2Fhome</a></p>
<p>With each revision of World Population Prospects (WPP), the Population Division carries out a re-estimation of historical demographic trends for countries and territories of the world. These demographic estimates are based on the most recently available data sources, such as censuses, demographic surveys, registries of vital events, population registers and various other sources. Newly available demographic data and information are subjected to quality analyses and evaluated by examining the consistency in the patterns, levels and trends of the data across countries and regions. The description of the guidelines for managing the quality of the data and process is available at: <a href="https://www.un.org/development/desa/pd/sites/www.un.org.development.desa.pd/files/unpd-egm-fer-2020-10-backgroundpaper_newtitle_final_oct9.pdf">https://www.un.org/development/desa/pd/sites/www.un.org.development.desa.pd/files/unpd-egm-fer-2020-10-backgroundpaper_newtitle_final_oct9.pdf</a>; <a href="https://population.un.org/wpp/Publications/Files/WPP2022_Methodology.pdf">https://population.un.org/wpp/Publications/Files/WPP2022_Methodology.pdf</a> </p>

<p>The adolescent birth rates reported for global and regional aggregates are based on the average of estimated adolescent birth rates for two, contiguous five-year periods (e.g., 2015-2020 and 2020-2025 for year 2020) published in United Nations, Department of Economic and Social Affairs, Population Division (2022), World Population Prospects 2022 (<a href="http://esa.un.org/unpd/wpp/">http://esa.un.org/unpd/wpp/</a>)</p>
<p>The age-specific fertility rates for global and regional aggregates from World Population Prospects (WPP) are based on population reconstruction at the country level and provide a best estimate based on all the available demographic information. WPP considers potentially as many types and sources of empirical estimates as possible (including retrospective birth histories, direct and indirect fertility estimates), and the final estimates are derived to ensure as much internal consistency as possible with all other demographic components and intercensal cohorts enumerated in successive censuses.</p>

<h2>Agregados regionales:</h2>
<p>Las tasas de natalidad en adolescentes indicadas para los agregados mundiales y regionales se basan en el promedio de las tasas de natalidad en adolescentes estimadas para dos períodos quinquenales contiguos (por ejemplo, 2015-2020 y 2020-2025 para el año 2020) publicadas en Naciones Unidas, Departamento de Asuntos Económicos y Sociales, División de Población (2017). <em>Perspectivas de la población mundial: La revisión de 2017, DVD Edition</em> (<a href="http://esa.un.org/unpd/wpp/">http://esa.un.org/unpd/wpp/</a>).</p>
<p>Las tasas de fecundidad específicas por edad para los agregados mundiales y regionales de las Perspectivas de la Población Mundial (PPM) se basan en la reconstrucción de la población a nivel de país y proporcionan la mejor estimación basada en toda la información demográfica disponible. Las PPM consideran y evalúan tantos tipos y fuentes de estimaciones empíricas como sea posible (incluyendo historias de nacimientos retrospectivas, estimaciones de fecundidad directas e indirectas), y las estimaciones finales se derivan para asegurar la mayor consistencia interna posible con todos los demás componentes demográficos y cohortes enumerados en censos sucesivos.</p>
