Wikidata Map October 2018

October 5, 2018 7 By addshore

It has been another 6 months since my last post in the Wikidata Map series. In that time Wikidata has gained 4 million items, 1 property with the globe-coordinate data type (coordinates of geographic centre) and 1 million items with coordinates [1]. Each Wikidata item with a coordinate is represented on the map with a single dim pixel. Below you can see the areas of change between this new map and the once generated in March. To see the equivalent change in the previous 4 months take a look at the previous post.

Comparison of March 26th and October 1st maps in 2018

Daniel Mietchen believes that lots of the increased coverage could probably be attributed to Cebuano Bot. (link needed).

Areas of increase

Below I have extracted sections of the map that have shown significant increase in items.

If you know why these areas saw an increase, such as a wikiproject or individual working on the area, then please leave a comment below and I’ll be sure to add explanations for each area.

If you think I have missed an area also please leave a comment and I’ll add that too!

Africa

Some areas within Africa can be picked out as having specific increases:

  • Republic of Cameroon
  • Gabonese Republic
  • Democratic Republic of the Congo
  • People’s Democratic Republic of Algeria
  • Republic of Djibouti

The increase in the coverage on the African continent in general by Wikidata could be down to Wikimania 2018 which was held in Cape Town. Cape Town itself doesn’t show any real increase in items in the 6 month period and is not included in the image above. Mexico also so an increase to the number of items in Wikidata in the area when Wikimania was hosted there in 2015.

Asia

The main areas of increase here appear to be:

  • Jakarta
  • Indonesia
  • Bangkok
  • North Korea

Europe

The main areas of increase here appear to be:

  • Scotland
  • Ireland
  • Norway
  • Finland
  • Latvia
  • Greece
  • Croatia
  • Cyprus (while not in europe) can be seen in the bottom right

North America

There is a general increase across the whole of North America. Most notably the west of continent and Canada.

The Dominican republic can also be seen in bright colour to the bottom right of the image.

South America

South America has a general increase throughout, however various areas appear highlighted such as:

  • Columbia
  • Chile
  • São Paulo & Brazil
