Older people should consider going to college so that you can continue working beyond the official retirement age, the minister for higher education has said.

David Willetts encouraged workers on the end in their careers to work out higher education as an option. “There’s certainly a pressure for continuing to get retrained and upskilled. Higher education has an economic benefit in that in the event you stay awake so far with knowledge and abilities, you’re more employable,” he told reporters as he travelled with the prime minister, David Cameron, in India.

“Education is this sort of great point – it’s not reserved for younger people. There’ll be people of every age who probably want to study. There’s great value in lifelong learning.”

Student loans were restricted to people under 54, however the government permits prospective students of any age to take out loans for fees. Loans to hide living costs are restricted to the under-60s.

“There has been plenty of criticism in regards to the ageism of all this. The regime now’s, there isn’t a age limit on fee loans,” Willetts told the Daily Telegraph. Per the upper Education Statistics Agency, only one,940 undergraduates starting courses last year were older than 60, out of a complete of 552,240 students in Britain. Some 6,455 were aged between 50 and 60.

Tuition fees are a maximum of £9,000 per year in England and scholars start repayments once they have a salary of £21,000. Most pensioners have an income of not up to £16,000, so would never need to repay their loans.

Today, 10 million people within the UK are over 65 years old. The newest projections are for 5½ million more elderly people in 20 years’ time, and the number could reach 19 million by 2050.

Within this total, the variety of very old people is determined to grow even faster. There are currently 3 million people aged greater than 80, and this figure is projected to just about double by 2030 and reach 8 million by 2050. The federal government estimates that the fastest-growing age group within the next decades might be people over 100.

As the collection of elderly people grows, so does the pension deficit; British pension schemes are estimated to have a complete deficit of £312bn.

Last year the home of Lords heard evidence of the effect of an ageing population on public policy. Simon Ross, the executive executive of Population Matters, told the Lords: “We should always expect and enable people to work later in life than prior to now. Employers and the federal government should consider what changes to employment practices are required to enable people to work longer.

“This will include changes to work premises and equipment, encouraging people to work at home, and being more flexible in regards to sick leave.”

“Given the pensions shortfall, a versatile labour market should enable the ‘fit old’ to work as many or few days a week as they feel essential to top up their very own pensions, notably providing a workforce to take care of the ‘unfit older’.”

Willetts said educational patterns were changing. “There may be evidence that the concept that you first study after which stop isn’t what the sector is like several more,” he said. “In the event that they can profit from it, they must have that chance. If people need it so as to sustain so far with changes of their jobs, which is a chance they will take.”
