Input: Question: Which city had a larger population the year Rimington moved to Essex, Essex or Wallasey? Passage:Rimington was born Stella Whitehouse in South London, England; her family moved from South Norwood to Essex in 1939, due to the danger of living in London during World War II. Her father got a job as chief draughtsman at a steel works in Barrow-in-Furness in Cumbria, and the family moved there and she was educated at Crosslands Convent School after spending some time in Wallasey. When her father got a job in Ilkeston, Derbyshire, the family moved to the Midlands, where Stella attended Nottingham High School for Girls. She spent her last summer of secondary school working as an au pair in Paris, before enrolling at the University of Edinburgh in 1954 to study English. By chance, she met her future husband, John Rimington, whom she had known from Nottingham.
