It's striking how there was very little change in the demographic makeup of Northern Ireland for the first 50 years after partition, followed by rapid change in the 50 years from 1971.

By the end of the 2020s we could end up with:

- Nigel Farage as Prime Minister
- TUV as the largest unionist party
- A nationalist plurality in Stormont

The shortest distance across the border from England to Scotland is over 130 miles
Google AI Overview

No, it's not possible to throw a paper plane from England to Scotland, as the flight distance between them is far greater than the maximum range of a paper airplane. The Guinness World Record for the longest distance flown by a paper airplane is only around 88 meters (290 feet), while the shortest distance across the border from England to Scotland is over 130 miles, requiring much more than a single throw. 
Here's why it's impossible:
Distance:
England and Scotland are separated by a significant landmass and body of water, with the narrowest points being over 100 miles wide.

I wonder why spending on schools in Northern Ireland has fallen so far behind GB since 2020.

Print sales are, amazingly, still the main revenue base for most mainstream local newspapers and cross-subsidise the online journalism. As the remaining print readers die, and with online ad revenue flatlining, that journalistic cross-subsidy will fall. So that's an 18% decline year-on-year.

An obviously unsustainable situation. When the Millennials approach retirement age, there will be fewer than 2 working age people for every person over 65 across Europe, with the ratio in Italy close to 1:1. Without enough taxpayers to pay for pensions the system will collapse.

Figures for the Belfast, Northern and South Eastern Trusts show that median times have increased since 2023, with one in twenty waiting around six years or longer on waiting lists (306 weeks).

Incredibly, it has now been nearly two years since the last Northern Ireland-wide hospital waiting statistics were published because of the ludicrous time it has taken to roll out the new "encompass" patient record system.

Until this year, Northern Ireland had cheaper electricity than the UK average, but prices are now marginally higher. Prices in the Republic are around 18% higher but NI still one of the most expensive electricity markets worldwide (prices 17% higher than France and 108% higher than the US).

Something I hadn't realised - Ireland has the most expensive electricity in the world (apart from 65k population Bermuda), with prices 59% higher than France and 2.4 times higher than average prices in the United States.

WWE Raw is coming to Belfast in 2026. It hasn’t had much notice outside wrestling circles, but it’s a major coup - the biggest international broadcast event from the city since the 2021 UEFA Super Cup.

By the 2050s Millennials will discover the state pensions system was a Ponzi: pay in for decades, collapse at payout. The electoral nihilism of the Boomers today will seem tame by comparison.

The UK and Ireland are far from the most severe amongst developed economies - by 2050 there will be around 1.2 people aged 25-64 for every person over 65 in Italy and Spain.

A massive shift underway in Ireland as well; when the early 80s baby boom approach retirement age there will be fewer than 1.8 people aged 25-64 for every person aged over 65, down from 5 in 2008.

In the UK in 1950 there were 5 people aged 25-64 for every person over 65. When the Millennials start to reach retirement age in the 2050s there'll be fewer than 2, falling to 1.4 by the end of the century. That seems... unworkable?

Surprising that the increase in the foreign born population in the UK in the 2020s wasn't that large by European standards over the period; much smaller than in Ireland or Austria. And the immigrant population % in the United States has barely increased since 2015.

The US-EU deal will greeted with the utmost sensitivity in Ireland, not just because pharma is still not out of the woods, but because it creates a differential in trading rates between Northern Ireland (10% as part of UK deal) and Republic of Ireland (15% as part of EU)

Looking at the updated UN migration data for 2024:

- Share of the UK population born abroad up 1.5 percentage points from 2020-24; lower than most other European states

- Ireland’s foreign-born population share rose by 4.0 points in four years; one of the highest rises globally

On votes at 16 for the 2029 GE in NI. Will mean around an extra 51k potential voters (people aged 8 or 9 at the 2021 census):

49% Catholic
33% Protestant
18% Other

The electorate in 2024 was 1.36m, so it will increase the number of potential voters by about 3.5%.
