What you should know about this indicator

  • This data comes from the LGBTI National Policy Dataset, compiled by Kristopher Velasco at Princeton University. It tracks the adoption, scope, and enforcement of 27 LGBTI-related policies across 195 countries, with annual data starting in 1991.
  • The indicator is coded as follows: Banned (conversion therapy is banned by law, executive order, or judicial ruling), Varies by region (bans differ between subnational jurisdictions) and Not banned (no national ban on conversion therapy).
  • A ban of any scope counts as Banned: bans that apply to everyone, bans that protect only minors, bans that bind only licensed health professionals (including indirect bans through mental-health laws that prohibit treating homosexuality as an illness), and bans that apply only in one kind of place, such as Ecuador’s ban in rehabilitation centers.
  • The dataset counts policies established by binding legal instruments — statutes, constitutional provisions, decrees and regulations with the force of law, and binding court rulings. Where no law governs a policy, a written rule that does can count too, such as a health-authority guideline, a blood service's donor questionnaire or a religious ruling. Bills, ministerial statements and non-binding declarations are not counted.
Conversion therapies banned
Velasco
Whether conversion therapy (practices that try to change a person's sexual orientation or gender identity) is banned, fully or in part, by law, executive order, or court ruling.

Velasco – LGBTI National Policy Dataset

The LGBTI National Policy Dataset (Version 3.0) is a country-year-policy panel tracking the adoption, scope, and enforcement of LGBTI-related policies across 195 countries from 1991 to 2025. The dataset is distributed in long format: each row records one country in one year for one specific policy-status combination, with the share of the population covered, the adoption and implementation years, the policy's descriptors (penalty, fine, sexes covered, scope, enforcement), up to twelve source citations and a confidence rating. It is designed for use in comparative political research, policy diffusion analysis, and quantitative cross-national studies of LGBTI rights.

The dataset covers 27 distinct policy areas organized into 54 policy-status combinations (each policy paired with two mutually exclusive status directions). Of these 54 combinations, 36 contain substantive data; the remaining 18 are structural placeholders with all-zero values, included to maintain a fully balanced panel suitable for econometric methods.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.

Notes on our processing step for this indicator

From the original dataset's single-direction proportion (0 = no policy, 1 = fully implemented, intermediate values = partial subnational adoption), we coded countries into three categories: the substantive direction in effect, partial subnational implementation ("Varies by region"), or no policy in effect.
