Background:
The HPOP Billion uses 16 outcome indicators related to social, environmental, and behavioral risks. At a population level, the index measures the number of people whose lives have become healthier by assessing the net change in one or more of the component indicators between 2018 and 2025.
-
About this tool:
This tool allows you to adjust the levels of HPOP tracer indicators to model what the effect would be on the overall HPOP Billion.
-
Instructions:
- 1. Change the baseline (2018) and 2025 projection values in the input boxes.
- 2. Click the CALCULATE button and see the effect of the changes on the number of newly healthier and newly unhealthier people, and the overall billion contribution (the net number of newly healthier people).
- 3. Click the Transformed values toggle button to view the indicator transformations used to calculate the Billion contribution (e.g. inversions or rescaling).

Methods
Indicators
Raw values for the tracer indicators undergo adjustments, for instance rescaling to a 0-100 scale or inversions so that positive change is a positive contribution to the Billion and negative change is a negative contribution to the Billion. These transformations can be seen by clicking the Transformed values toggle button.
Number of newly healthier/unhealthier lives
The change in transformed indicator values between 2018 and 2025, multiplied by the relevant 2025 population for the indicator. For example, for alcohol this is the population aged over 15, whereas for childhood stunting it is the population of children under 5.
Billion contribution
The net number of newly healthier lives (i.e. total newly healthier lives total newly unhealthier lives) -

INSTRUCTIONS: Default values reflect those in the Triple Billion dashboard, and are preliminary projections, subject to change. Change the baseline (2018) and 2025 projection values by entering values in the input boxes, and then click the 'CALCULATE' button. Click the Transformed values toggle button to view the indicator transformations used to calculate the Billion contribution (for instance, inversions or rescaling).
