UK - Alternate Coloring

[DistingFlyer]

Here's a little experiment: UK maps from 1955 to 1997 with a new shading system. For each election - using Sibboleth's outlines, I hasten to add - I've made one map indicating the percentage majority and one indicating the percentage of the total vote.

The color key is the same for both categories of map.

1955




1959




1964




1966




1970




1974 (Feb)




1974 (Oct)




1979




1983




1987




1992




1997

Beautiful maps, great job!

I have to say, UK may be pretty close to the US in terms of population-density distortion. Even 1997 looks like a tie in area terms!

[DistingFlyer]

Here are maps for 2001.

I've also got data for 1950 & 1951 - does anyone have an editable Boothroyd map for those boundaries? It would be nice to put up those years too.

[DistingFlyer]

Now, to bring things up to date, here are maps for 2005 & 2010:

2005




2010

[Wake Me Up When The Hard Border Ends]

Great maps, not only for their content, but also for how the boundaries have changed over the years.

Does anyone know where to get the Northern Ireland Shapefiles?

Credit actually belongs to David Boothroyd.

[Filuwaúrdjan]

Interesting work though.

No, but these maps weren't drawn that way anyway.

Ah.  They seem to be really hard to find if they exist. While Westminster shapefiless for Great Britain are easy to find, being part of the Boundary-Line package from the Ordinance Survey, I emailed the NI elections office, and their response was 'what's a shapefile?'

[Filuwaúrdjan]

lol

Northern Ireland isn't covered by the UK Ordnance Survey. To be fair to the Electoral Office for Northen Ireland, they probably have more dodgy electoral incidents to monitor than their peers do. They published shapefiles for the latest, abortive revision of boundaries that ended in 2013.

I've done outline maps that sort of correct Boothroyd's 'circus mirror' distortion if they are of any help.

[ObserverIE]

Land and Property Services Northern Ireland (into which OSNI was folded a few years back) is not part of the UK government's OpenData initiative, so while there are shapefiles available for administrative geographies such as parliamentary constituencies, they operate on the basis of a sizeable annual licence fee.

In addition, the people running LPS NI decided on April 1 to announce:

There is no word as to when the new website will become available.

What's available at the moment, is the set of NISRA's census geography files at:

http://www.nisra.gov.uk/geography/SOA_.htm

SOAs can be nested into wards, which in turn can be nested into parliamentary constituencies.

Alternatively, if you feel like doing some web service querying, and conversion of JSON into shapefiles, there is:

That sounds good - which redistributions do you have?

[afleitch]

Just 1983 onwards for now. 1974 is almost done and that will allow me to work backwards. I've done them from 1950 onwards in another version which I didn't like

[afleitch]

And 1974 at last.

[DistingFlyer]

And 1974 at last.

Lovely!

Have started filling in these outlines with the new color scheme - what did the original Milton Keynes SE border look like in 1992? Pretty much the same as '97 (the northern border, anyway)?

Also, am I blind or is Lewisham West missing from the 1983 map?

[🐒Gods of Prosperity🔱🐲💸]

great maps.

The past few decades have not been kind to the Tories in Scotland, esp. since '97.

Probably is I had to do and hand paint by paint job. Should be easy to fill in.

I'd be really interested to see one of these maps for 1945 (one of my favorite elections ever). Does anyone have the data for that year, or is it too far back?

[EPG]

The data are out there, but the map is rather difficult to produce, because some of the constituencies were only used at the 1945 election and their boundaries are not well documented on the WWW. I'm sure someone on this forum has done it. In the interim, here is a 1945 majorities map, shaded by a continuous rather than discrete scale:



Image created with the UK-Elect software and FWS Craig's results and boundaries guides. Boundaries are correct in approximately 98% of cases.

[Antonio the Sixth]

That's really cool, thank you!

[DistingFlyer]

Here's 1983, using afleitch's new map - more to come:

[DistingFlyer]

And here's 1974, take two:

And 1979:
