Searching quantitative data for historians: 3. Via statistical databases

Introductory notes

Direct search (in known database)
When you know a database, you will have Statistics is a category you can select in the list of search engines of the University Library. Most selected search engines below are freely accessible on the internet, except for the OECD database (you will have to log in with your solisID). 

Indirect search (for more databases)
Feel free to search for more statistics with Google. Keep in mind a few things when formulating keywords:
- Statistics are not always explicitly presented in the form of a database (keywords: statistics OR "statistical data" combined with a relevant keyword)
- 'Statistics' is often used for statistical data (keywords: statistics OR statistical combined with a relevant keyword)
- Search official statistics of a country (keywords: "United States" OR American; or use a URL-extension as a keyword, i.e. '.cn' for China)  
- Use the language of the country you are researching: (données) statistiques (French), (statistische) Daten / Statistiken (German),  (dati) statistiche (Italian), datos (estadisticos) / estadisticas (Spanish) etc. 

Statistical databases are not aiming at historians and often contain little historical data. Search for an Archive section or look for filter options by year to see how far back data reach.


(i) Any organised collection of data may be considered a database. In this sense the word is synonymous with dataset.
(ii) A software system for processing and managing data, including features to extend or update, transform and query the data.

Note: In the context of this LibGuide, the word database is exclusively used in the second definition. 
Note: database sometimes is spelled as two words:data base. Its synonym databank can be spelled 'data bank'. 

Government data

The work of government involves collecting huge amounts of data, much of which is not confidential (economic data, demographic data, spending data, crime data, transport data, etc). The value of much of this data can be greatly enhanced by releasing it as open data, freeing it for re-use by business, research, civil society, data journalists, etc. Source: Open Data Handbook

Open Data

Data is open if it can be freely accessed, used, modified and shared by anyone for any purpose - subject only, at most, to requirements to provide attribution and/or share-alike. Specifically, open data [...] requires that the data be A. Legally open: that is, available under an open (data) license that permits anyone freely to access, reuse and redistribute B. Technically open: that is, that the data be available for no more than the cost of reproduction and in machine-readable and bulk form.

Statistical databases: local data

Here two examples of statistical databases from the Netherlands: the historical data is provided in another website. The official website for national statistics, StatLine, has a very limited functionality "archive". For the country you do research about, check the official online statistics. It is variable how far back in time data is available. Try the statistics databases in the box below for variables concerning your country
