More than 660 people were caught watching TV without a licence in Lincoln last year.
This compares with more than 340 people in Gainsborough and more than 110 people in Sleaford.
TV Licensing also revealed the average evasion rate is just over 5 per cent, which means almost 95 per cent of homes in Lincolnshire are properly licensed.
Mark Whitehouse, TV Licensing spokesman for East Anglia, said: "The data released shows evasion remains at historically low levels of approximately 5 per cent.
"That means the overwhelming majority of people have ensured they are correctly licensed.
"In order to be fair to the law-abiding majority who do pay for their licence, we'll continue to pursue the small minority of people who do not pay.
"We do understand some people may find it difficult to pay in one go, which is why we offer numerous ways to spread the cost."
A colour TV licence currently costs £145.50 and is required by anyone watching or recording TV programmes on TV or a computer.
People who do so without a licence are risking court prosecution and a fine of up to £1,000.
