Kettering is in the top 20 places in the UK with the highest growth in households, according to the findings of the 2011 census.
And it will continue to expand, said borough council leader Russell Roberts, in a responsible and well-planned manner.
Kettering saw households increase by 16.8 per cent between 2001 and 2011, putting it at sixth place in the UK top 20.
In 10 years its population rose from 82,300 to 93,500, an increase of 13.6 per cent.
Mr Roberts said: “What we are looking for is responsible growth, to lift the infrastructure and build new homes in a responsible way. We will be using the data from the census, along with a whole raft of other information, to plan growth and seek funding.
“We have already enjoyed success with the Government’s commitment to widen the A14 and with the funding which is being made available for the A43 Corby bypass.”
The number of households in East Northants increased by 15.2 per cent, putting it at 14th in the top 20 for growth in households. Its population rose from 76,800 in 2001 to to 86,800 in 2011, an increase of 13 per cent.
The population of Wellingborough increased from 72,500 to 75,400 in the past 10 years.
The census shows the county’s population has risen to 692,000 and the latest figures will be used by local authorities when seeking Government funding. A county council spokesman said: “Northamptonshire has been earmarked as one of the key areas for population and economic growth in the country. We need to conduct further analysis on the figures to get a more detailed breakdown of the numbers.
“The population figures can be presented to Government to attract further funding for infrastructure to accommodate the growth.”
