The Initial Report of the Boundary Commission in 1947 made minor changes to the constituency, in line with local government changes which had abolished Guisborough Rural District in 1932 and absorbed it into Whitby Rural District. The new constituency again included the whole of Whitby Rural District, and so gained Hinderwell which was previously within Cleveland constituency. It had an electorate of 67,884 on 15 October 1946. No change was made in the First Periodical Report of the Boundary Commission in 1954.
The Second Periodical Report, published in 1969 recommended that the constituency be divided and its recommendations came into effect at the February 1974 general election abolishing the seat. The Scarborough constituency was thereby re-established, and Whitby joined with Guisborough, Loftus, Saltburn and Brotton to form Cleveland and Whitby.
By the beginning of the Third Periodical Report of the Boundary Commission, Cleveland had been created as a new county, which would normally prevent the commission from recommending a constituency crossing the border. Several representations were made to the commission to try to preserve Cleveland and Whitby constituency, but the Commission found itself unable to accept them and recommended putting Scarborough and Whitby together in a new Scarborough despite including the other coastal town, its old name, including Whitby, was finally reinstated in the next review.[n 4] This constituency did not include Pickering, which was placed in a new Ryedale constituency.
In the Fourth Periodical Report of the Boundary Commission for England, published in 1995 and coming into effect at the 1997 general election, the Scarborough constituency was renamed as Scarborough and Whitby with no change in boundaries.
When the constituency was recreated in 1997, the Labour candidate, Lawrie Quinn, defeated John Sykes, the sitting Conservative MP – one of many locally and national press-predicted unlikely gains for Labour in their landslide victory of that year. The current incumbent, Robert Goodwill, defeated Quinn in 2005 to regain the seat for Conservatives.

The constituency covers the towns of Scarborough and Whitby. Both of these are seaside towns in North Yorkshire on the north-east coast of England. However, the constituency is largely rural and semi-rural, such issues tend to influence voting preferences, with Scarborough itself mostly Labour and the rural areas Conservative. At the last two general elections, it was the most marginal seat in North Yorkshire.
The constituency consists of Census Output Areas of a Borough with a working population whose income is close to the national average and lower than average reliance upon social housing. At the end of 2012 the unemployment rate in the constituency stood as 4.8% of the population claiming jobseekers allowance, compared to the regional average of 4.7%. The borough has a medium-high 28.8% of its population without a car, a high 26.0% of the population without qualifications and a medium 22.7% with level 4 qualifications or above.
In terms of tenure, a high 75.8% of homes are owned outright or on a mortgage as at the 2011 UK Census across the borough.
Another general election was required to take place before the end of 1940. The political parties had been making preparations for an election to take place from 1939 and by the end of this year, the following candidates had been selected;
