The views expressed here are not those of my employer.&lt;/em&gt;&lt;/p&gt; &lt;p&gt;The 2024 election is behind us, but there is still discussion about electoral reform following the introduction of independent candidates and the separate regional ballot. Consequently I thought it would be interesting to update my &lt;a href=&quot;https://x.com/adrianfrith/status/1279721244670210050&quot;&gt;imagined demarcation of single-member constituencies&lt;/a&gt; for 2024.&lt;/p&gt; </description> <pubDate>Sun, 07 Jul 2024 00:00:00 -0500</pubDate> <link>https://adrian.frith.dev/single-member-constituencies/</link> <guid isPermaLink="true">https://adrian.frith.dev/single-member-constituencies/</guid> </item> <item> <title>Census API and website updates</title> <description>&lt;p&gt;Since 2013, &lt;a href=&quot;https://census2011.adrianfrith.com/&quot;&gt;a website I developed&lt;/a&gt; has provided information on places from the South African National Census of 2011. Recently I’ve developed a &lt;a href=&quot;https://graphql.org/&quot;&gt;GraphQL&lt;/a&gt; API to make that data available to other developers. In parallel with this API development, I’ve also added some extra data, and made some changes to the website. Read on for more details.&lt;/p&gt; </description> <pubDate>Sun, 17 May 2020 00:00:00 -0500</pubDate> <link>https://adrian.frith.dev/census-api-website/</link> <guid isPermaLink="true">https://adrian.frith.dev/census-api-website/</guid> </item> <item> <title>Western Cape number plate map updated</title> <description>&lt;p&gt;I’ve updated &lt;a href=&quot;/wc-number-plates/&quot;&gt;my Western Cape number plate map from 2014&lt;/a&gt; to include the new CAA code for Cape Town.&lt;/p&gt; &lt;figure&gt; &lt;a href=&quot;/images/western-cape-number-plates.png&quot; target=&quot;_blank&quot;&gt;&lt;img src=&quot;/images/western-cape-number-plates-thumb.png&quot; alt=&quot;Map of the Western Cape province, South Africa, showing the number plate codes issued by different towns in the province.&quot; /&gt;&lt;/a&gt; &lt;figcaption&gt;Western Cape number plate prefixes&lt;/figcaption&gt; &lt;/figure&gt; </description> <pubDate>Wed, 09 Oct 2019 00:00:00 -0500</pubDate> <link>https://adrian.frith.dev/wc-number-plates-updated/</link> <guid isPermaLink="true">https://adrian.frith.dev/wc-number-plates-updated/</guid> </item> <item> <title>A gallery of recent maps</title> <description>&lt;p&gt;This post presents a selection of maps I have produced in the last few weeks.

Since then the state of the technology for web mapping has moved on, so I’ve developed a completely new version. This new map uses vector tiles for better rendering, includes results for four general elections (2004–2019), and allows you to drill all the way down to voting district level. &lt;a href=&quot;https://elections.adrianfrith.com/&quot;&gt;And here it is.&lt;/a&gt;&lt;/p&gt; &lt;figure&gt; &lt;a href=&quot;https://elections.adrianfrith.com/&quot; target=&quot;_blank&quot;&gt;&lt;img src=&quot;/images/new-election-map-screenshot.png&quot; alt=&quot;A screenshot of a site titled 'South African Election Results' and showing the results of the 2019 election by ward.&quot; /&gt;&lt;/a&gt; &lt;/figure&gt; </description> <pubDate>Fri, 31 May 2019 00:00:00 -0500</pubDate> <link>https://adrian.frith.dev/new-interactive-election-map/</link> <guid isPermaLink="true">https://adrian.frith.dev/new-interactive-election-map/</guid> </item> <item> <title>Linguistic diversity map of South Africa</title> <description>&lt;p&gt;The &lt;a href=&quot;https://en.wikipedia.org/wiki/Linguistic_diversity_index&quot;&gt;linguistic diversity index&lt;/a&gt; measures the probability that two people selected at random from a population speak different home languages. The map below, which I produced, depicts the linguistic diversity index calculated on a 10-kilometre-wide hexagonal grid across South Africa.&lt;/p&gt; &lt;figure&gt; &lt;a href=&quot;/images/linguistic-diversity.png&quot; target=&quot;_blank&quot;&gt;&lt;img src=&quot;/images/linguistic-diversity-thumb.png&quot; alt=&quot;A map of South Africa showing the linguistic diversity index calculated on a 10-kilometre-wide hexagonal grid&quot; title=&quot;Linguistic diversity map of South Africa&quot; /&gt;&lt;/a&gt; &lt;figcaption&gt;Linguistic diversity; click to enlarge&lt;/figcaption&gt; &lt;/figure&gt; </description> <pubDate>Wed, 09 Aug 2017 00:00:00 -0500</pubDate> <link>https://adrian.frith.dev/linguistic-diversity/</link> <guid isPermaLink="true">https://adrian.frith.dev/linguistic-diversity/</guid> </item> <item> <title>Historical topographic maps of Cape Town</title> <description>&lt;p&gt;I’ve made &lt;a href=&quot;http://htonl.dev.openstreetmap.org/50k-ct/&quot;&gt;an interactive website with six sets of topographic maps of Cape Town and surrounds&lt;/a&gt; covering the period from 1940 to 2010. You can zoom in and move around the maps, switching from one era to another.&lt;/p&gt; </description> <pubDate>Sun, 01 Nov 2015 00:00:00 -0500</pubDate> <link>https://adrian.frith.dev/historical-maps-of-ct/</link> <guid isPermaLink="true">https://adrian.frith.dev/historical-maps-of-ct/</guid> </item> <item> <title>South African provinces as they might have been</title> <description>&lt;p&gt;The post-apartheid political map of South Africa might well have looked quite different. The Eastern Cape might have been divided into two provinces, with the Kat River and Great Fish River on the boundary. The Northern Cape might not have existed, with the Western Cape meeting North West at the Orange River. Gauteng might have been much bigger – or much smaller. The Western Cape might have stopped south of Citrusdal – or it might have incorporated all of Namaqualand.&lt;/p&gt; </description> <pubDate>Fri, 14 Aug 2015 00:00:00 -0500</pubDate> <link>https://adrian.frith.dev/provinces-might-have-been/</link> <guid isPermaLink="true">https://adrian.frith.dev/provinces-might-have-been/</guid> </item> <item> <title>How many people live in countries where same-sex marriage is legal?</title> <description>&lt;p&gt;After the recent US Supreme Court ruling legalising same-sex marriage (SSM) throughout that country, a claim was recently brought up &lt;a href=&quot;https://en.wikipedia.org/wiki/Talk:Same-sex_marriage#One_billion_milestone&quot;&gt;on a Wikipedia talk page&lt;/a&gt; that more than one billion people now live in countries (or states/provinces) where SSM is legal. I thought I’d check out the numbers, and update my old graph showing how this has changed over time.&lt;/p&gt; </description> <pubDate>Sat, 04 Jul 2015 00:00:00 -0500</pubDate> <link>https://adrian.frith.dev/ssm-population-stats/</link> <guid isPermaLink="true">https://adrian.frith.dev/ssm-population-stats/</guid> </item> </channel> </rss>
