This dataset provides regional estimates for the indicators in the OLAS/SCL WASH Household Survey Dataset: https://mydata.iadb.org/Water-and-Sanitation/OLAS-SCL-WASH-Household-Survey-Dataset/bjat-gfsm

For information on how the dataset was generated, please refer to the methodology document.

This dataset was generated by the Knowledge team in the Inter-American Development Bank’s Water and Sanitation division from publicly available information to allow for the characterization and comparison of tariff systems and subsidies. It contains data on residential drinking water supply and sanitation tariffs, and includes data on subsidies, tariff types, metering, and more.

The tariff dataset has been simplified and made available to the public via the Water and Sanitation Observatory for Latin America and the Caribbean (OLAS), consistent with the OLAS’s goals to provide consistent, reliable, and updated data to understand the water and sanitation sector at the national and regional levels, within the framework of SDG 6.

For more information about this process and general trends in the dataset please see "How Much Do Households Pay for Water Supply and Sanitation Services in Latin America? A Descriptive Analysis of Tariffs and Subsidies in the Region."

This dataset is an interpolated version of the OLAS/SCL Household Survey Data Set, and includes data from Latin America and Caribbean countries from 2003-2023. The interpolation can be used for understanding trends in water and sanitation access in the region.

The OLAS/SCL Household Survey Data Set contains 47 water and sanitation related indicators generated from microdata from national household surveys throughout the region. The data set contains information from 2003-2022 for 22 countries throughout Latin America and the Caribbean. Indicators are provided in terms of household percentage and total households that fall into each category, and can be broken down by various socioeconomic dimensions, including area (urban or rural community), income quintile, migratory status, ethnicity, and disability status. This dataset is the result of a collaboration between INE/WSA and SCL, and is a subset of the larger IDB SCL Indicators dataset.

The OLAS LAPOP 2018-2019 dataset provides information on water and sanitation access for 18 countries across Latin America and the Caribbean. The dataset uses microdata from the 2018-2019 wave of the AmericasBarometer project from Vanderbilt’s Latin America Public Opinion Project (AB-LAPOP).

The AB-LAPOP is a comparative survey that aims to create a temporal data set for the western hemisphere that includes a broad range of topics, produced by a standardized method and the use of a common core questionnaire which permit valid comparisons across countries and over time on topics. Technical information on the sampling methods and survey design can be access for each country surveyed on the LAPOP website. The OLAS LAPOP 2018-2019 dataset focuses on water and sanitation access information, covering topics like type of water source used by households for different purposes, continuity of access, type of sanitation facility and whether households have exclusive access.

The OLAS LAPOP 2021 dataset provides information on water and sanitation access for 18 countries across Latin America and the Caribbean. The dataset uses microdata from the 2021 wave of the AmericasBarometer project from Vanderbilt’s Latin America Public Opinion Project (AB-LAPOP).

The OLAS Simplified GLAAS for LAC dataset provides information on water and sanitation governance in 30 countries across Latin America and the Caribbean (LAC) from 2018 and 2021. The data is from the UN-Water Global Analysis and Assessment of Sanitation and Drinking-Water (GLAAS), which is a global survey carried out by UN Water and the World Health Organization (WHO) that collects country-level information on provision of water, sanitation, and hygiene services. The survey covers topics like governance, monitoring, finance, and human resources in the sector. This simplified version of the dataset contains information relevant to WASH governance in LAC.
