Under Construction

Project purpose

The Global Consumption and Income Project (GCIP) aims to provide a deeper understanding of the evolution of material well-being both within and across countries, for regions and the world as a whole, extending from description to interpretation and explanation.

As part of the effort we developed two separate datasets (the Global Consumption Dataset (GCD) and the Global Income Dataset (GID)) containing a portrait of consumption and income of persons over time, within and across countries, across the world .

The datasets, based on underlying surveys, present estimates of monthly real consumption and income for arbitrarily specified quantiles of the population (a ‘consumption/income profile' for deciles in the benchmark version) for the vast majority of countries in the world (more than 160) for every year for more than half a century (1960-2015) in 2005 PPP dollars (extendable to market exchange rates and other PPP base years and concepts).

We intend to provide the database and the in-built tools for analysis to interested researchers, government, international organizations, public interest organizations, and the general public. GCIP provides a high standard of transparency and documentation, allowing for third-party replication, updating and the adoption of alternate assumptions for the selection and treatment of data from the underlying universe, unlike current databases. We aim to update the database on an ongoing basis if suitable resources can be found. We welcome all enquiries from possible supporters and partners. The first version of the database can be downloaded from this website.
