The Olympics workforce has reached 7,000 on the £8 billion construction project.
Latest employment and skills figures from the Olympic Delivery Authority showed that 4,842 people were working on the Olympic Park construction site in east London.
A further 2,428 people were working on the Olympic Village, taking the total to 7,270.
More than one in five Olympic Park workers are resident in one of the five Host Boroughs, while more than half live in London.
ODA chairman John Armitt said: “The big build of the Olympic Park and Village is on track and providing vital employment, training and business opportunities in London and across the UK.
“Our steady progress on regenerating this part of east London is testament to the workforce on site and hard work of thousands across the UK whether they are fabricating steel in Wales for the Aquatics Centre or growing wetland plants in Norfolk for the parklands.”
