Countries with the Largest National Open Data Portals in 2026

Most governments now run a national open data portal, a single website where ministries, agencies and often cities publish free, reusable data on everything from bus timetables to air quality. Back in 2019, RList counted 88 countries with one, holding close to 1.2 million datasets between them. Here are the 14 biggest in 2026, ranked by the number of datasets each national portal lists. Counts change daily and every portal counts a little differently, so each figure is the one the portal (or its official reporting) published at the time of writing, in 2026. Sources are named below. The EU's data.europa.eu isn't a country portal, so it's left out. So is the UK, because data.gov.uk is being rebuilt as a smaller, curated National Data Library and no longer publishes a comparable total.

The Top 10

#1

United States — 604,910 datasets

Data.gov, run by the General Services Administration, is still the giant of government open data. Its catalog listed 604,910 datasets in September 2026, more than twice the 261,090 RList counted in 2019. Those datasets come from more than 120 federal, state, city, university and tribal publishers, and in 2025 the catalog moved off its old CKAN software onto a new custom-built system. Exact totals vary a little depending on where you look, because some similar datasets are grouped into “collections” that can be counted once or many times.[1][16]

#2

India — 230,000+ datasets

India's Open Government Data Platform gives one point of access to data from the country's ministries, departments and agencies. It held more than 230,000 datasets as of July 2026. Its own counters slice things more finely still: 623,178 individual resources (files and data feeds) grouped into 13,090 catalogs.[2]

#3

Germany — 169,221 datasets

GovData is a metadata portal: it doesn't store the files itself, but pulls together listings from federal, state and municipal open data sites into one search. That design has let it grow fast, from about 96,555 datasets in March 2024 to 169,221 in 2026, including 18,902 of the EU's specially designated “high-value” datasets.[3]

#4

Australia — 141,395 datasets

Data.gov.au listed 141,395 datasets at the end of September 2026, up from 85,234 in RList's 2019 count. Among its recent additions are a national waste and resource recovery database and state rental bond data, the kind of everyday figures that make these portals useful.[4][16]

#5

South Korea — 107,901 datasets

Korea's Public Data Portal started in 2013 with 5,272 datasets. It passed 100,000 at the end of 2024 and topped 107,900 by August 2026, about 20 times where it began. Data comes from around 1,100 institutions, from central ministries to the National Assembly, and public administration, culture and tourism are the biggest topics. Korea doesn't just publish a lot: it has also ranked first in the OECD's OURdata Index of open data policy four times in a row.[5][15]

#6

Spain — ~100,000 datasets

Spain's national catalog, datos.gob.es, reached almost 100,000 datasets in 2025, containing more than half a million individual files. Like GovData, it collects listings from regional and local governments across the country as well as national bodies, which is why its count is rounded here.[6]

#7

France — 74,631 datasets

Data.gouv.fr lists about 74,600 datasets and keeps adding them quickly: 2,265 new ones in July 2026 and 1,678 more in August. France pairs size with quality too, coming second only to Korea in the OECD's 2023 OURdata Index.[7][15]

#8

Italy — 57,437 datasets

Italy's national catalog, dati.gov.it, shares 57,437 datasets with the EU's data.europa.eu portal. The EU's 2025 Open Data Maturity report rated about 60% of their metadata (the descriptions that make data findable) “excellent” and the rest “good”, putting Italy's catalog first among EU member states for metadata quality.[8]

#9

Austria — 55,665 datasets

Data.gv.at lists 55,665 datasets from 1,356 organisations, and 765 apps built on that data. Some reports put its own counter at over 57,600, which would nudge it just past Italy, so these mid-table places are close. Since September 1, 2025, Austria's Freedom of Information Act has required public bodies to actively publish data that isn't specially protected, so the count should keep rising.[9]

#10

Taiwan — 52,437 datasets

Taiwan's Government Data Open Platform lists 52,437 datasets from central and local agencies. It even publishes data about itself: a downloadable list of every dataset on the platform and figures for how often each one is viewed and downloaded.[10]
