Taking its name from the River Ogmore, the constituency was close to the source of the river in the Ogwr valley, but it excluded the village of Ogmore-by-Sea, south-west of Bridgend (Pen-y-bont ar Ogwr).{{refn|Ogmore-by-Sea forms part of the Vale of Glamorgan County Borough and of the Vale of Glamorgan constituency).|group= n}} Ogmore constituency covered the area of Bridgend County Borough Council roughly north of the M4, and parts of Rhondda Cynon Taf County Borough Council. It included the communities of Cefn Cribwr, Garw Valley, Gilfach Goch, Llanharan, Maesteg, Ogwr Valley, Pencoed, Sarn, and Tondu.{{cite web|title=Ogmore Constituency Labour Party|url=http://www.cobwebs.uk.net/oclp/page1.html|access-date=2008-08-28|publisher=Ogmore Labour|date=2008-07-20|archive-url=https://web.archive.org/web/20160603032713/http://www.cobwebs.uk.net/oclp/page1.html|archive-date=3 June 2016|url-status=usurped}}

;Major boundary change

A substantial change of boundaries took effect in 1983, when the new constituency of Bridgend was created, centred on the town of that name, which was by then the largest settlement in Ogmore. The constituency since that date consisted of the northern part of the original constituency, together with wards from the former Borough of Taff-Ely (now Rhondda Cynon Taf CBC).

;Summary of winning results

The 2015 result made the seat the 44th-safest of Labour's 232 seats by percentage of majority.{{cite web |url=http://www.ukpolitical.info/labour-mps-elected-2015.htm |title=Labour Members of Parliament 2015 |website=UK Political.info |archive-date=2018-09-29 |archive-url=https://web.archive.org/web/20180929214847/http://www.ukpolitical.info/labour-mps-elected-2015.htm |url-status=live}} Successive candidates fielded by the Labour Party have won absolute majorities (pluralities) since the seat was created in 1918, or have run unopposed four times. The 2019 election was the first time in the seat's 101-year history that Labour failed to win an absolute majority, though the party still won with a margin of 22%

;Opposition parties

Four parties have taken the runner-up position from and including a 2002 by-election, a total of five elections. At the 2015 general election the Liberal Democrat, Green and TUSC candidates did not win 5% of the vote apiece therefore forfeited their deposits. Those running for the Conservatives and UKIP in 2015 (and 2016 at the by-election held during the month before the UK's EU membership referendum) held their deposits. The highest polling of any runner-up, by percentage, was Thomas George Jones in 1931, winning 30.8% of the votes cast, 0.3% more than half the percentage polled by the winning candidate; this was when the Labour Party's vote was slightly split by the presence of a prominent Communist Party candidate and editor, Johnny Campbell. The government's dropping of a prosecution against him in 1924 had led to a General Election.

;Turnout

Turnout at general elections has ranged between 85.3% in 1950 and 57.8% in 2005, falling to 35.2% in the 2002 by-election.
