X Percent of the Population of Scotland Lives Within Y Miles of Edinburgh

Follow up from the Glasgow post by request.

This is a pretty easy question to answer, using the 2011 Scottish Census population results and the Census Output Area Population Weighted Centroids. Then we get the extents of Edinburgh City Council from OS Boundary Line.

The results are:

,Pop. Count:,%
Scotland, 5295403, 100
Edinburgh , 476626, 9
25 km, 1276757, 24.1
50 km, 2500093, 47.2
50 miles, 3919910, 74
100 km, 4310869, 81.4
100 miles, 4812421, 90.9

So we see more than people live close to Glasgow, but with 50 miles + they are closer to the capital.

To see how these boundaries look on a map:

Population buffers around Edinburgh

A few caveats:
We are using the population weighted centroids, which will produce some minor inaccuracies, but is a very good generalisation.
Also we are using euclidean buffers on the British National Grid plain, so these are not geodesic buffers. The difference will likely be small at these distances.

Mapvember 2014

Mapvember: A map/tutorial a day for every day in November.

Some days had more than one map, some had tutorials, one just had a photo. Some were very easy, others would have take a couple of days of work.

Excellent experience, good learning experience and an opportunity to post previous projects that were a bit short of being great. A little time consuming at times though. I started making the maps around half way through October, so I had almost the first week ready when November began, but the days ticked by quickly. Happy to have done it. I encourage everyone to join in next year, or any other month.
