Boundary changes for the 2010 general election transferred the community of Whitburn into the neighbouring South Shields seat. Pelaw and Heworth transferred from the abolished constituency of Gateshead East and Washington West. (The Wrekendyke ward had been renamed Wardley and Leam Lane).
As a result of 2023 Periodic Review of Westminster constituencies the consistency was abolished with new constituencies being contested in the 2024 general election. Jarrow constituency was split between modified South Shields and newly created Jarrow and Gateshead East the following way:

The last Liberal to serve the seat lost his seat at the 1922 general election and the last Conservative to serve the seat held it from 1931 to 1935, since which it has been served by MPs from the Labour Party.
Since 1935, just five people have served as MP for Jarrow; the first, Ellen Wilkinson, served as Labour's first Minister of Education during the first Attlee government. While the seat has been loyally Labour by comfortable margins since 1935, it has seen unusual swings a number of times; in the 1983 Conservative landslide, incumbent MP Don Dixon actually increased his majority; in the close 1992 election his majority fell somewhat despite the general swing to Labour; and in 2001 his successor Stephen Hepburn managed to increase his majority to 51.1% (incidentally the biggest any candidate has ever held in the seat).
