Global population data

This indicator provides values for final consumption expenditure expressed in current international dollars, converted by purchasing power parities (PPPs). PPPs account for the different price levels across countries and thus PPP-based comparisons of economic output are more appropriate for comparing the output of economies and the average material well-being of their inhabitants than exchange-rate based comparisons. Households and NPISHs final consumption expenditure includes expenditure on goods and services by the Household and NPISH sector for the direct satisfaction of human needs or wants, whether individual or collective. This series has been linked to produce a consistent time series to counteract breaks in series over time due to changes in base years, source data and methodologies. Thus, it may not be comparable with other national accounts series in the database for historical years. This indicator is expressed in current prices, meaning no adjustment has been made to account for price changes over time. The PPP conversion factor is a currency conversion factor and a spatial price deflator. PPPs convert different currencies to a common currency and, in the process of conversion, equalize their purchasing power by eliminating the differences in price levels between countries, thereby allowing volume or output comparisons of GDP and its expenditure components.

The percentage of people using improved sanitation facilities that are not shared with other households and where excreta are safely disposed of in situ or transported and treated offsite. Improved sanitation facilities include flush/pour flush to piped sewer systems, septic tanks or pit latrines: ventilated improved pit latrines, composting toilets or pit latrines with slabs.

The LandMark Indigenous and Community Lands dataset is the product of an on-going initiative to map and document the collectively held and used lands and natural resources of Indigenous Peoples and local communities globally (landmarkmap.org). LandMark aggregates maps from numerous local, national, and regional sources into one standardized global dataset based on identity (Indigenous Peoples or local community) and legal recognition status (acknowledged or not acknowledged by government). These areas are displayed as polygons (boundaries) or locational points (when boundaries are not available). The dataset is not complete – experts believe that 50% or more of the world’s land is held or used by Indigenous Peoples and local communities, while coverage of this dataset is a fraction of this; therefore, the absence of data does not mean an absence of indigenous or community land. Data contributions can be submitted to LandMark(). Categories of LandMark Indigenous and community lands are defined as follows: - Indigenous Lands - Acknowledged by Government: lands that are recognized in law as being held or used by peoples who self-identify as indigenous - Indigenous Lands - Not acknowledged by Government: lands that are held or used by peoples who self-identify as indigenous, but the lands are not recognized as such in law; includes lands that are in process of obtaining recognition or customary tenure with no recognition in process - Community Lands - Acknowledged by Government: lands that are recognized in law as being held or used by local communities - Community Lands - Not acknowledged by Government: lands that are held or used by local communities, but the lands are not recognized as such in law; includes lands that are in process of obtaining recognition or customary tenure with no recognition in process - Indicative Areas of Indigenous and Community Lands: areas where indigenous- and community-held lands are likely to exist, but the clear delimitation and/or recognition status of these lands is not currently available. The purpose of this category is to promote awareness of the extent of Indigenous Peoples’ and local communities’ lands even in the absence of detailed demarcation data. More information about the data and typology can be found on LandMark’s [methodology page](). Depicts Indigenous Peoples’ and local communities’ lands and territories as locational points (due to lack of boundary information), classified according to a standard global typology based on identity (Indigenous or community) and legal recognition status.

Age dependency ratio, young, is the ratio of younger dependents--people younger than 15--to the working-age population--those ages 15-64. Data are shown as the proportion of dependents per 100 working-age population.

Prevalence of overweight, female, is the percentage of girls under age 5 whose weight for height is more than two standard deviations above the median for the international reference population of the corresponding age as established by the WHO's 2006 Child Growth Standards.

Estimated density of people per grid-cell, approximately 1km (0.008333 degrees) resolution. The units are number of people per Km² per pixel, expressed as unit: "ppl/Km²". The mapping approach is Random Forest-based dasymetric redistribution. The WorldPop project was initiated in October 2013 to combine the AfriPop, AsiaPop and AmeriPop population mapping projects. It aims to provide an open access archive of spatial demographic datasets for Central and South America, Africa and Asia to support development, disaster response and health applications. The methods used are designed with full open access and operational application in mind, using transparent, fully documented and peer-reviewed methods to produce easily updatable maps with accompanying metadata and measures of uncertainty.

Depositors with commercial banks are the reported number of deposit account holders, including both resident non-financial corporations (both public and private) and individuals from the household sector, at commercial banks within the reporting jurisdiction for every 1,000 adults.

Population in urban agglomerations of more than one million is the country's population living in metropolitan areas that in 2018 had a population of more than one million people.

Population living in slums is the proportion of the urban population living in slum households. A slum household is defined as a group of individuals living under the same roof lacking one or more of the following conditions: access to improved water, access to improved sanitation, sufficient living area, housing durability, and security of tenure, as adopted in the Millennium Development Goal Target 7.D. The successor, the Sustainable Development Goal 11.1.1, considers inadequate housing (housing affordability) to complement the above definition of slums/informal settlements.
