EXCLUSIVE Revealed: The towns that have seen the biggest population growth since the 1990s - including one which has doubled in size... so is YOURS one of them?

Britains most crowded borough has doubled in population since the early 1990s, MailOnline analysis shows.

Tower Hamlets population has spiralled from 166,300 to just shy of 328,600.

It means there are now more than 16,400 residents per square kilometre in the east London district, the most densely populated zone in the country. 

That is, for comparison, 633 times more than in Powys, Wales – the least densely populated authority with just 25.95 people per square kilometre.

Experts claim Tower Hamlets growth explosion lays bare the staggering reality of uncontrolled immigration.

Almost half of residents living there were born outside of the UK, 46.8 per cent, as per the last Census.

Immigration levels have since shot to all-time highs, meaning the true figure within Tower Hamlets now could be even higher.

Soaring populations heap even greater pressure on housing, schools and the ailing NHS.

MailOnline can reveal populations in 10 authorities in England and Wales have grown by at least 50 per cent since 1991, when modern records began.

Behind Tower Hamlets came neighbouring borough Newham, increasing by 67.7 per cent from 216,300 to 363,600.

Milton Keynes ranked third, jumping 67.3 per cent from 178,200 to just north of 298,300.

Ten authorities also saw their populations shrink over the same time-frame, when excluding Scotland and Northern Ireland, who did not have 2023 data.

This included Blaenau Gwent, traditionally a coal mining community in south Wales.

Its population shrank by 7.3 per cent, from 72,600 to around 67,300.

Dr Ben Brindle of the Migration Observatory told MailOnline: Migration has been the main driver of UK population growth over the past decade, particularly since 2020, when net migration rose sharply and the gap between births and deaths fell. This is not unique to London – the foreign-born share of the population has increased across the UK.

London is the most popular destination within the UK for international migrants, but overall population growth is actually slightly lower in London than most other regions. That is because London sees a net outflow of people to the rest of the UK.

England’s population stood at 57.1million in 2022, according to the Office for National Statistics’ (ONS) latest report.

 It is expected to surpass 64m in 2042. For comparison, around 47.9m people lived in England 1991.

Back then, 2.8m people were recorded as living in Wales. This hit 3.1m in 2022 and is forecast to rise to 3.4m by 2042.

By 2122, the population of the UK is predicted to hit 81.6m, with England expected to house almost 71.3m people. 

Alp Mehmet, Chairman of think tank Migration Watch told MailOnline: Official figures from the ONS have revealed projected population growth by mid-2032 of almost five million people and of almost ten million people by 2047. This astonishing increase will be entirely due to immigration and the children of migrants. The projections are based on the assumption that net migration will fall to an annual 340,000, from 2029, which is unlikely without radical policy change.

Net migration hit an all-time high of almost one million last year in the UK.

This year alone, almost 7,000 migrants have arrived on small boats, with record numbers of people packed onto each boat – with one vessel intercepted carrying 71 passengers.

In the year to June 2023, the ONS said 1.32m people immigrated here, mainly from India, Nigeria, Pakistan, China and Zimbabwe. Another 414,000 emigrated.

It meant around 906,000 people – the equivalent to Leicester-sized cities – settled in Britain.

That excludes natural changes to the population, with births outnumbering deaths and only adding to the strain of Britain’s public services.

Soaring populations will pile pressure on ministers to build millions more homes.

Builders aren’t even hitting the current target of 300,000 homes a year.

In order to meet Labour’s building blitz pledge, some councils have been to build seven times as many houses.

Thousands more GPs will also be needed to keep up.

Under the widely accepted ‘safe’ limit, one fully-qualified, full-time equivalent GP is needed for every 1,800 patients.

In February there were just 28,000 in England – well below the 35,500 needed by 2042 is current trends continue.
