Aylesbury expanded significantly after World War II, in a diverse way with a similar proportion of this recent development being social housing estates as private estates.
Workless claimants who were registered jobseekers were in November 2012 lower than the regional average of 2.4% and national average of 3.8%, at 2.2% of the population based on a statistical compilation by The Guardian.
Whereas the average house price is higher than the national average, in the Aylesbury Vale authority (which largely overlaps) this in the first quarter of 2013 was £262,769, the lowest of the four authorities in Buckinghamshire and this compares to the highest county average of £549,046 in South Bucks District.
The seat was a much narrower, generally urban borough with two-member status at Westminster from its grant of a limited franchise in 1553 until the passing of the Great Reform Act 1832. Unusually, the contents of the Parliamentary Borough were defined within the Act itself to include the "Three Hundreds of Aylesbury". This extended the seat to include Wendover and Princes Risborough. The Borough continued to elect two MPs until its abolition by the Redistribution of Seats Act 1885 and transformation into a large county division, formally named the Mid or Aylesbury Division of Buckinghamshire. It was one of three divisions formed from the undivided three-member Parliamentary County of Buckinghamshire, the other two being the Northern or Buckingham Division and the Southern or Wycombe Division. As well as the areas previously represented by the abolished Borough, the reconstituted seat included Linslade to the north-east and Chesham to the south-east. Since then national boundary reviews have seen a gradual reduction in its physical size as its population has grown (see Boundaries Section below).
The Conservative Party has held the seat since 1924, and held it at the 2015 general election with a 50.7% share of the vote. The result made the seat the 133rd safest of the Conservative Party's 331 seats by percentage of majority. The closest result since 1929 was in 1966 when the Labour Party candidate fell 7.4% short of a majority.

1945–1950: The House of Commons (Redistribution of Seats) Act 1944 set up Boundaries Commissions to carry out periodic reviews of the distribution of parliamentary constituencies. It also authorised an initial review to subdivide abnormally large constituencies in time for the 1945 election. This was implemented by the Redistribution of Seats Order 1945 under which Buckinghamshire was allocated an additional seat. As a consequence, the parts of the (revised) Rural District of Wycombe in the Aylesbury Division, including Hughenden and Princes Risborough (but not Wendover which had been moved from the Rural District of Wycombe to that of Aylesbury by the reorganisation of local authorities in Buckinghamshire), were transferred to Wycombe.

Hughenden transferred from Wycombe. Princes Risborough transferred to Buckingham, offset against return of Aston Clinton. Great Missenden returned to Chesham and Amersham.
The constituency is based on the large town of Aylesbury and its suburbs as well as a small swathe of villages broken up by woods and cultivated land in the centre of the Chilterns which cover most of Buckinghamshire and parts of three other counties.
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; *Conservative:
On the original count, both Smith and Wentworth received 535 votes, meaning there were three MPs elected. However, after scrutiny, Wentworth lost one vote and was declared unduly elected on 2 August 1859.
