CountryData function

I under that Mathematica are able to extract data from a cloud/ online sources. Pardon the improper use of jargon for programming and IT is not my area of familiarity.

Are the data that Mathematica is able to extract limited? I am interested in, for instance, extracting the number of hospitals and clinics within a country, and, number of person above a certain age in a country.

Would Mathematica be able to achieve?

• Are you asking just about the data curated by Wolfram, or about importing data from any source on the web? See Import[] for the latter. – Michael E2 Jul 27 '16 at 13:27
Yes, the data that Mathematica is able to obtain via CountryData and other curated data functions is limited. The data is curated, which means that it is assembled by WRI from a variety of sources, and you only have access (via this mechanism) to data that WRI has made available. You can find a good description of the available properties in the Details section of the CountryData documentation, or a straight list using CountryData[country, "Properties"].
