API for Economic Data


Using the Quandl API for Economic Data

This document is a comprehensive guide to using the Quandl API to access our economic data.The mechanism for accessing economic data via the Quandl API is no diferent from the mechanism for accessing all data on Quandl. The purpose of this help page is mainly to explain the specific publishers and nomenclature for economic data.

For further information on the Quandl data API, read our general API reference. You can also access Quandl data directly from within the analysis tool of your choice – Stata, SAS, R, Python, Matlab, Maple, EViews and more – using our free tools. Quandl is the easiest way to find and download current and historical economic data.

To start using the Quandl API:

  1. Sign up for a free API key
  2. Find the data you need: use the list below or use our search page.
  3. Start making calls: use our API reference page to learn the syntax.

Free Unlimited API for Economic Data

Quandl provides a free, unlimited and unrestricted API for global economic data, including macroeconomic, demographic and social statistics.

Quandl unifies free data from the World Bank, UN, Eurostat, ADB, BEA, BLS, FRED and many more data publishers, in a single easy-to-use and powerful economic data API. Quandl also offers premium economic databases from specialist data vendors, guaranteed to be accurate, comprehensive and up-to-date, via the same API.

Quandl’s API offers access to 1000s of economic indicators for every country in the world. Data publishers include regional and multinational organizations, central banks, government statistical departments, research agencies and think tanks. Indicators cover growth, inflation, employment, domestic and internationsl trade, industry, agriculture, services, capital markets, government finances, aid, education, gender, health, poverty, disease, mortality, population, and much much more. All of these datasets are accessible via a single uniform API, documented on this page.

Basic Economic Data API Usage

International and regional statistical organizations often collect data for the same indicator across multiple countries, suitably harmonized and synchronized. For such economic indicators that exist across countries, the Quandl code generally follows one of these two formats:




where {PUBLISHER} identifies the data publisher, {COUNTRY} is the ISO 3-letter code of the country, and {INDICATOR} is a publisher-specific code for the indicator in question. The country code and the indicator code are separated by an underscore.

For example, the ISO 3-letter code for China is “CHN”. The publisher named “WORLDBANK” has data for total population under the indicator code “SP_POP_TOTL”. Hence the full Quandl code for the Population of China as published by the World Bank is WORLDBANK/CHN_SP_POP_TOTL.

Here is a list of all ISO 3-letter country codes.

Central banks and government agencies typically publish single-country economic statistics, hence the above nomenclature pattern does not apply to them.

Example API Call

For quick learners, here is an example of a Quandl API call for economic data:

The above call gets the government bill rate (column 2) from the dataset titled “Interest Rates – Canada”, published by the UN, sorted in ascending date order, from the start of 1980 to the end of 1990, annual observations, in CSV format.

Many more transformations and manipulations of the data are available; see our full API reference for more details.

Data Publishers

Quandl covers data from over 500 different publishers, many of whom provide economic statistics. For economic data, these publishers generally fall into 6 categories:

  • International Organizations. This includes the UN, World Bank, IMF, WHO, FAO, WTO, ILO and similar institutions.
  • Regional Organizations. This includes the OECD, ADB, Eurostat, ECB and others.
  • Central Banks. Quandl has data from about 30 different central banks. The most comprehensive central bank databases are published by the Bundesbank, BOE, BCB and the Federal Reserve.
  • Government Agencies. The US government publishes a huge amount of data, via the DOE, BEA, BLS, USDA, CENSUS and other agencies. Other countries with excellent statistical agencies include Canada, Brazil, France, UK, Australia and Germany,
  • Researchers. There are a number of excellent cross-country surveys, including LIS, Penn, GGDC / Maddison, Brinkhoff and EPI.
  • Premium Publishers. These are specialist economic data providers who provide high-quality harmonized cross-country data for a fee.

Individual economic data publishers are described in detail below.

Note that most international and regional organizations do not collect or measure primary economic data themselves; they merely collate data that was originally published by central banks and single-country statistical agencies. This leads to certain limitations that are explained at the end of this guide.

International Organizations

World Bank

The World Bank has one of the most comprehensive (and best-documented) collections of international economic and statistical data. All economic datasets published by the World Bank can be found on the WORLDBANK page and follow the code format WORLDBANK/{COUNTRY}_{INDICATOR}.

The World Bank’s data is organized into 22 databases corresponding to specific areas of coverage. For a list of available databases and their descriptions, please refer to the WORLDBANK documentation page


The International Monetary Fund publishes several different databases, covering global economic and financial statistcs. However, not all of theses databases are freely available. Quandl’s IMF database contains the subset of IMF data that is freely available under the publisher name ODA. This subset includes most major economic indicators in the World Economic Outlook (WEO) database.

All of the ODA datasets follow the code format ODA/{COUNTRY}_{INDICATOR}. For a list of all available indicators, please refer to the IMF documentation page.

United Nations

The United Nations Statistical Division (UNSD) collects data from a number of primary and secondary sources, and publishes it in harmonized format. UNSD’s data coverage is vast and comprehensive, and includes economic, societal, demographic, and environmental data. Datasets from UNSD on Quandl are listed under publisher name UNDATA, and they all follow the code format UNDATA/{INDICATOR}_{COUNTRY}.

The UNDATA database is made up of 15 component databases, each covering a different subject area. For a list of all available databases and their Quandl codes, please refer to the UNDATA documentation page.

More Global Data

Quandl has data from a number of other international and regional organizations, listed below. Visit each organization’s documentation page to see its respective dataset nomenclature conventions on Quandl.

Country Statistics

In addition to cross-country statistics published by multi-national organizations, most countries in the world collect and publish their own domestic data. Single-country data is usually more “granular” than cross-country data (more frequent observations, more indicators surveyed) but cannot easily be compared or harmonized.

Single-country data is usually published by central banks and by national statistical agencies. Quandl has a number of both. Here are some of the central bank databases available on Quandl:






St Louis Fed


Huge collection of US and international economic data


Bank of England


Includes excellent foreign exchange data collection




German and European time-series economic data


Central Bank of Brazil


Brazilian and global data including commodites


Bank of France


Banking activities of French banks with non-residents


Bank of Japan


Japanese macroeconomic data


People’s Bank of China


Chinese macroeconomic data

Some of the above central banks — notably FRED, BCB, BOE and Bundesbank — publish a great deal of international data in addition to domestic indicators. Here is a full list of 25+ central bank databases available on Quandl and via the economic data API.

Here are some of the national statistical agency databases available on Quandl:





Statistics Canada



Brazilian Institute of Geography and Statistics



National Institute of Statistics France

Flaws in Free Data

Free data from international organizations suffers from a few limitations.

First, the data is by definition “secondary”; it is aggregated from a multitude of sources (individual central banks, statistical agencies, surveys, governments and so on). This almost always introduces transcription and translation errors. The very best aggregators (e.g. UNSD) have robust processes in place to minimze these errors, nonetheless many mistakes do persist.

Second, data obtained from international organizations has limited or no transparency to the original publisher. This makes it difficult to confirm numbers as well as methodology. Complete transparency is the best way to avoid data-pipeline errors, but this option is not always available.

Third, multinational aggregators collect and publish data annually at best. This is true even when their respective primary sources publish data monthly or quarterly. As a result, the aggregated data is often outdated or stale.

Fourth, despite the annual frequency limit, the “updating time” can be very slow. For example, the IMF’s flagship WEO survey for a given calendar year is only released in October of the following year. This may be too late for many time-sensitive or predictive applications.

Fifth, the quality of documentation for public data sources varies hugely. Some publishers provide excellent documentation; many others do not.

Premium Data

In order to avoid the limitations detailed above, we now provide a professional grade economic database to our users. The Standard Global Economics (SGE) database collects 7000+ harmonized macroeconomic indicators for over 200 countries, going back up to 100 years.The data is collected from 1000+ sources, including central banks, statistical agencies, and research institutions.

The datasets in this premium economic database are collected directly from their primary publishers, with complete transparency to source. The data is as granular as possible, with monthly observations in most cases, and quarterly when monthly is not available. The data is updated immediately after the publisher updates, based on a pre-defined economic calendar. The data is comprehensive, perfectly organized and documented, and goes back decades.

Each dataset in the SGE database has a Quandl code of the format SGE/{ISO}{INDICATOR}, where ISO is a 3-letter country code and `{INDICATOR} is a harmonized indicator code. The indicators include GDP, population, inlation, unemployment, government budget, and many other macroeconomic indicators.

To see a list of all available indicators, country ISO codes, and Quandl code examples, please visit the SGE documentation page.
