Ms Rourke took over as acting national statistician earlier this year, after her predecessor retired through ill health.
Critics said her decision to wear the flag, which indicates a belief that there are more than two biological sexes and that transwomen are women, was an “ostentatiously political move”.
Civil servants are expected to be impartial under the civil service code and uphold the Nolan Principles of public life, while earlier this year the Supreme Court ruled that transwomen were not legally women.
Ms Rourke took over from Sir Ian Diamond who stepped down last month due to health issues.
Before that, she was deputy national statistician for health, population and methods, which meant she oversaw the ONS debacle on sex and gender identity.
At her first “ONS Live” event for all ONS staff, Rourke said she had an “uncomfortable message” for staff about Sir Robert Devereaux’s forthcoming review into ONS culture, expected to be released imminently.
She said: “It is likely to continue to be difficult for us as an organisation – we are experiencing ongoing challenges in being able to stabilise our suite of core statistics.”
