The average life expectancy for women in Bassetlaw could be 86 by 2030, a new study has found.
Men are also set to live longer than official estimates predict as the historic gender gap narrows.
In England and Wales the average life expectancy for women could be approaching 90 by 2030.
The study, based on Office for National Statistics data combined with advanced mathematical modelling, suggests that average life expectancy for women will rise from 83.3 in 2012 to 87.6 in 2030. For men, it is predicted to increase from 79.5 to 85.7 over the same period.
The figures for Bassetlaw show women could be approaching 86-years-old by 2030 and men could reach 85.
The forecasts for 2030 are higher than those issued by the Office for National Statistics by 2.4 years for men and one year for women.
But the upward trend masks significant regional differences, the research shows.
By 2030, people in affluent southern England and well-off districts of London are expected to be living more than eight years longer than those in northern urban centres such as Blackpool, Liverpool and Manchester, as well as South Wales.
