High-resolution gridded population datasets for Latin America and the Caribbean in 2010, 2015, and 2020.

Sorichetta A, Hornby GM, Stevens FR, Gaughan AE, Linard C, Tatem AJ - Sci Data (2015)

Bottom Line: The Latin America and the Caribbean region is one of the most urbanized regions in the world, with a total population of around 630 million that is expected to increase by 25% by 2050.In this context, detailed and contemporary datasets accurately describing the distribution of residential population in the region are required for measuring the impacts of population growth, monitoring changes, supporting environmental and health applications, and planning interventions.All these products are available both through the WorldPop Project website and the WorldPop Dataverse Repository.

ABSTRACT
The Latin America and the Caribbean region is one of the most urbanized regions in the world, with a total population of around 630 million that is expected to increase by 25% by 2050. In this context, detailed and contemporary datasets accurately describing the distribution of residential population in the region are required for measuring the impacts of population growth, monitoring changes, supporting environmental and health applications, and planning interventions. To support these needs, an open access archive of high-resolution gridded population datasets was created through disaggregation of the most recent official population count data available for 28 countries located in the region. These datasets are described here along with the approach and methods used to create and validate them. For each country, population distribution datasets, having a resolution of 3 arc seconds (approximately 100 m at the equator), were produced for the population count year, as well as for 2010, 2015, and 2020. All these products are available both through the WorldPop Project website and the WorldPop Dataverse Repository.

Estimated people per grid cell for Latin America and the Caribbean in 2010 (excluding Guadalupe, Martinique, Bahamas, Barbados, Saint Lucia, Curaçao, Aruba, Saint Vincent and The Grenadines, US and British Virgin Islands, Grenada, Dominica, Cayman Islands, Saint Kitts and Nevis, Sint Maarten, Turks and Caicos Islands, Saint Martin, Caribbean Netherlands, Anguilla, Saint Barthélemy, and Montserrat).The grid cell resolution is 3 arc seconds (approximately 100 m at the equator) and coordinates refer to GCS WGS 1984. For illustrative purpose, the color ranges used are country-specific.

These datasets were then projected to 2010 (Fig. 3), 2015, and 2020 using UNPD rural and urban growth rates25 and also adjusted to match the most recent UNPD estimates at the time of writing25.
