Definitions

Data source performance index are based on the Statistical Performance Indicators (SPI) Pillar 4 index and is a composite measure of whether countries have data available from (i) censuses and surveys, (ii) administrative data, and (iii) geospatial data.
Data infrastructure performance index are based on the SPI Pillar 5 index and refer to the capability of the statistical system. It measures standards and methods addressing compliance with recognised frameworks and concepts.
Please refer to information on Statistical Performance Indicators (SPI) at World Bank's SPI website.

Concepts

The new SPI replaces the Statistical Capacity Index (SCI), which the World Bank has regularly published since 2004. Although the goals are the same, to offer a better tool to measure the statistical systems of countries, the new SPI framework has expanded into new areas including data use, administrative data, geospatial data, data services, and data infrastructure. The SPI provides a framework that can help countries measure where they stand in several dimensions and offers an ambitious measurement agenda for the international community.

Computational Method

An overall score is produced by combining the Statistical Performance Indicators to yield one single index. The statistical performance indicators have a nested structure, and the SPI Pillar 4 and Pillar 5 scores are formed by sequentially aggregating each level. To begin we produce a score for each dimension, which, unless otherwise stated, is an unweighted average of the indicators within that dimension. After computing a score for each dimension, a score for the pillar is computed as an unweighted average of the dimensions in that pillar.

Data Collection

The World Bank transparently shares and makes public the methodologies for all adjustments to original data (e.g., through its SPI website and its various analytical documents). All code and data to generate the SPI scores is available on the SPI public github repository.
