There will be nearly 100,000 more living in the county by 2037, according to the Quality of Life in Warwickshire report.
And “affordable decent housing” in the Leamington, Warwick and Kenilworth areas was identified as an issue needing improvement.
The annual report for Warwickshire County Council uncovered findings ranging from earnings and employment, to house prices and population.
Of the estimated 624,000 county population by 2037, it said that one in six will be aged over 75 – around 100,000. Currently about one in 12 of the population is aged over 75, just over 40,000 people.
The report says that while the ageing population can have health and social care implications, it can also have positives with increased volunteering, spending power and charitable donations. It says the population growth will be varied, with the Warwick District Council area going from the 2012 figure of 139,000 to 160,000 in 2037, up 15.1 per cent.
Rugby Borough Council area is predicted to increase to 120,000, up 18.9 per cent, and the Stratford District Council area up 11.5 per cent to 135,000.
But North Warwickshire will only see an 8.4 per cent increase to 67,000, and Nuneaton and Bedworth up 13.4 per cent to 143,000.
There is good news for earnings in Warwickshire over the last year, with the average wage going up by four per cent, ahead of the regional and national figures.
The report’s Index of Multiple Deprivation highlights nine areas in Warwickshire that feature in the 10 per cent most deprived communities in the country, with all nine in Nuneaton and Bedworth Borough.
The report said there were 1,100 people long-term unemployed in the county, with half of them living in Nuneaton and Bedworth – 12 years ago the proportion was one fifth.
There is good news for education in Warwickshire, with pupils performing well at both Key Stage 2 and Key Stage 4, outperforming their regional and national counterparts.
County council chief executive Jim Graham said: “Earnings are up, education is performing well, and crime and anti-social behaviour is falling. On our roads the number of people killed or seriously injured has fallen by four per cent, and has more than halved in the last 12 years.”
But he added: “I’m concerned the levels of inequality in Warwickshire are growing.”
