‘In stories like this, the data and the methodology are key’: when private equity meets public service journalism

A team from across the Guardian set out to investigate the full extent of private equity’s stake in Britain’s public and essential services. The scale and opacity posed many challenges

When Carmen Aguilar García began investigating the involvement of private equity firms in England’s childcare sector with her fellow data journalists three years ago, she didn’t imagine her efforts would one day be scaled up to examine private equity’s role in the entire UK economy. That ambitious undertaking by Carmen and colleagues from across the Guardian was published earlier this week.

“The initial investigation into the childcare sector in 2023 was already challenging and a big team effort,” says Carmen, a data projects editor at the Guardian. “Extrapolating it to the whole economy did not seem realistic back then.”
