Wilson was born at 4 Warneford Road, Huddersfield, in the West Riding of Yorkshire, England, on 11 March 1916. He came from a political family: his father James Herbert Wilson (1882–1971) was a works chemist who had been active in the Liberal Party and then joined the Labour Party. His mother Ethel (née Seddon; 1882–1957) was a schoolteacher before her marriage; in 1901 her brother Harold Seddon settled in Western Australia and became a local political leader. When Wilson was eight, he visited London and a much-reproduced photograph was taken of him standing on the doorstep of 10 Downing Street. At the age of ten he went with his family to Australia, where he became fascinated with the pomp and glamour of politics. On the way home he told his mother, "I am going to be Prime Minister."
Wilson won a scholarship to attend Royds Hall Grammar School, his local grammar school (now a comprehensive school) in Huddersfield in Yorkshire. His father, working as an industrial chemist, was made redundant in December 1930, and it took him nearly two years to find work; he moved to Spital in Cheshire, on the Wirral, in order to do so. Wilson was educated in the Sixth Form at the Wirral Grammar School for Boys, where he became Head Boy.

Wilson did well at school and, although he missed getting a scholarship, he obtained an exhibition; this, when topped up by a county grant, enabled him to study Modern History at Jesus College, Oxford, from 1934. At Oxford, Wilson was moderately active in politics as a member of the Liberal Party but was strongly influenced by G. D. H. Cole. His politics tutor, R. B. McCallum, considered Wilson as the best student he ever had. He graduated in PPE (Philosophy, Politics and Economics) with "an outstanding first class Bachelor of Arts degree, with alphas on every paper" in the final examinations, and a series of major academic awards. Biographer Roy Jenkins says:
Academically his results put him among prime ministers in the category of Peel, Gladstone, Asquith, and no one else. But...he lacked originality. What he was superb at was the quick assimilation of knowledge, combined with an ability to keep it ordered in his mind and to present it lucidly in a form welcome to his examiners.
He continued in academia, becoming one of the youngest Oxford dons of the century at the age of 21. He was a lecturer in Economic History at New College from 1937, and a research fellow at University College.
On New Year's Day 1940, in the chapel of Mansfield College, Oxford, he married Mary Baldwin who remained his wife until his death. Mary Wilson became a published poet. They had two sons, Robin and Giles (named after Giles Alington); Robin became a professor of Mathematics, and Giles became a teacher. In their twenties, his sons were under a kidnap threat from the IRA because of their father's prominence.
On the outbreak of the Second World War, Wilson volunteered for military service but was classed as a specialist and moved into the civil service instead. For much of this time, he was a research assistant to William Beveridge, the Master of University College, working on the issues of unemployment and the trade cycle. Wilson later became a statistician and economist for the coal industry. He was Director of Economics and Statistics at the Ministry of Fuel and Power in 1943–44, and received an OBE for his services.
He was to remain passionately interested in statistics, becoming a Fellow of the Royal Statistical Society in 1943. As President of the Board of Trade, he was the driving force behind the Statistics of Trade Act 1947, which is still the authority governing most economic statistics in Great Britain. He was instrumental as Prime Minister in appointing Claus Moser as head of the Central Statistical Office, and was president of the Royal Statistical Society in 1972–73.
