There s a lot of ambiguity about population it all depends on what you think Chippenham is At the 2001 census Chippenham CP had a pop n of 28 065 Census 2001 Chippenham CP Headcount If you include Chippenham Without CP and Langley Burrell Without CP which some might but this includes the population of a few surrounding villages then you d have a total of 33 832 Chippenham Town Council estimate the population to be over 40 000 Someone put a figure of 33 189 in the article again quoting from the 2001 Census but I can t equate this to the data available I put an approximate figure of 30 000 in the infobox based on the 2001 census data What is the right figure to use
