Health Equity Assessment Toolkit (HEAT)

The Health Equity Assessment Toolkit (HEAT) is a software application for use on desktop or laptop computers and mobile devices (minimum screen size of 7.9 inches recommended). It was developed to facilitate the assessment of within-country health inequalities. HEAT is organized around two main components:

  • Explore inequality, which enables users to explore the situation in one country of interest to determine the latest situation of inequality and the change in inequalities over time.
  • Compare inequality, which enables users to benchmark, i.e. compare the situation in one country of interest with the situation in other countries.

Inequalities can be assessed using disaggregated data and summary measures that are visualized in a variety of interactive ways, including tables and graphs. Customized results can be exported and saved in different formats.

The Built-in Database Edition, Version 1.1 is available as an online application and as a standalone version for download. HEAT contains data from the WHO Health Equity Monitor database (2016 update).
