Dataset overview

Rank Title Description Best Avg.
1 Government Budget

National government budget at a high level, that is the planned government expenditure for the upcoming year, and not the actual expenditure. Open budget data allows for well-informed publics: showing where money is spent on, how public funds develop over time, and why certain activities are funded. We recommend that you consult our methodology section for more information.

1 National Statistics

Key national statistics on demographic and economic indicators such as Gross Domestic Product (GDP), or unemployment and population statistics. See our methodology section for more information.

3 Procurement

All tenders and awards of the national/federal government aggregated by office. It does not look into procurement planning or other procurement phases. Open procurement data may enable fairer competition among companies, allow to detect fraud, as well as deliver better services for governments and citizens. Monitoring tenders helps new groups to participate in tenders and to increase government compliance. The Index draws on work from the Open Contracting Partnership. See our methodology for more information.

4 National Laws

This data category requires all national laws and statutes to be available online, although it is not a requirement that information on legislative behaviour e.g. voting records is available.

100% Brazil  Canada  Sweden  Northern Ireland  Netherlands  Austria  Japan  50%
5 Administrative Boundaries

Data on administrative units or areas defined for the purpose of administration by a (local) government. See our methodology section for more information.

100% Belgium  Brazil  Australia  Austria  Bangladesh  Great Britain  United States  Uruguay  Canada  Colombia  France  Italy  Greece  Netherlands  Taiwan  Singapore  New Zealand  Romania  Northern Ireland  Paraguay  45%
6 Draft Legislation

Data about the bills discussed within national parliament as well as votings on bills (not to mix with passed national law). Data on bills must be available for the current legislation period. Open data on the law-making process is crucial for parliamentary transparency: What does a bill text say and how does it change over time? Who introduces a bill? Who votes for and against it? Where is a bill discussed next, so the public can participate in debates? This data category draws on work by the National Democratic Institute (NDI) and the Declaration of Parliamentary Openness.

7 Air Quality

Data about the daily mean concentration of air pollutants, especially those potentially harmful to human health. Data should be available for all air monitoring stations or air monitoring zones in a country. The Index focusses on key pollutants as defined by the World Health Organisation. See our methodology section for more information.

100% Puerto Rico  Taiwan  Great Britain  Hong Kong  Colombia  Northern Ireland  Belgium  40%
8 National Maps

A geographical map of the country including national traffic routes, stretches of water, and markings of heights. The map must at least be provided at a scale of 1:250,000 (1 cm = 2.5km). Geographic information is instrumental for many use cases, including the mapping of unemployment statistics or demographics, as well as journey planning. See our methodology section for more information.

100% Brazil  Canada  Australia  Finland  United States  Great Britain  Germany  Netherlands  37%
9 Weather Forecast

3-day forecasts of temperature, precipitation and wind. Forecasts have to be provided for several regions in the country. Short-term weather forecasts are relevant for the general public to plan activities, while also being reliable. See our methodology section for more information.

100% Slovenia  Sweden  Taiwan  United States  Puerto Rico  Norway  Argentina  35%
10 Company Register

List of registered (limited liability) companies. The submissions in this data category do not need to include detailed financial data such as balance sheet, etc. Open data from company registers may be used for many ends: e.g. enabling customers and businesses to see with whom they deal, or to see where a company has registered offices. This definition draws on the work of OpenCorporates.

100% Russia  Great Britain  Australia  Canada  Japan  Northern Ireland  Argentina  France  Norway  Singapore  Taiwan  Ukraine  Thailand  29%
11 Government Spending

Records of actual (past) national government spending at a detailed transactional level. Data must display ongoing expenditure, including transactions and subsidies. A database of contracts awarded or similar will not be considered sufficient. Open spending data shows whether public money is efficiently and effectively used. It helps to understand spending patterns, and to display corruption, misuse, and waste. We recommend that you consult our methodology section for more information.

12 Election Results

This data category requires results by constituency / district for all major national electoral contests. Election data informs about voting outcomes and voting process. What are electoral majorities and minorities? How many votes are registered, invalid, or spoilt? To enable highest transparency, the Index assesses polling station data. Data for electoral zones does not suffice. The Index consulted the National Democratic Institute (NDI) to develop this data category. For more information, see the NDI’s Open Elections Data Initiative. We recommend that you consult our methodology section for more information.

13 Locations

A database of postcodes/zipcodes and the corresponding spatial locations in terms of a latitude and a longitude (or similar coordinates in an openly published coordinate system). The data has to be available for the entire country. See our methodology section for more information.

100% Austria  Australia  Denmark  Taiwan  Slovakia  Norway  Mexico  13%
14 Water Quality

Data, measured at the water source, on the quality of water is essential for both the delivery of services and the prevention of diseases. The Index either looks at the quality of designated drinking water sources, or of environmental water sources (if drinking water data is not available). See our methodology for more information. In order to satisfy the minimum requirements for this category, data should be available on level of the following chemicals by water source.

85% Northern Ireland  Taiwan  United States  New Zealand  Japan  12%
15 Land Ownership

Data should include maps of lands with parcel layer that displays boundaries in addition to a land registry with information on registered parcels of land. The Index focuses on assessing open land tenure data (describing the rules and processes of land property). Responsible use may enable tenure security and increase the transparency of land transactions. The assessment criteria were developed in collaboration with Cadasta Foundation. For more information on land ownership datasets and where they're located, check out Cadasta Foundation's Data Overview.

Note: The methodology used in the Global Open Data Index has changed over time; significantly so between 2015 and 2016. For this reason, the results are not directly comparable over time.
