Forty-six per cent of Biden's transition staff are people of colour, according to the new diversity data of the transition team provided to CNN, and 41% of the senior staff are people of colour. The majority of transition staff -- 52% -- are women, and 53% of the senior staff are women.

The new diversity figures come as Biden is set to announce his Cabinet picks and senior staff for the White House in coming weeks  -- one of the first tests of his campaign pledge to build an administration that will "look like America."

Biden's first major step toward diversity in his administration came when he selected Kamala Harris, a Black and South Asian woman, as his Vice President. In his first staffing announcement, Biden chose a White man and long time advisor -- Ron Klain -- as his Chief of Staff for the White House.

The transition team's diversity also extends to its advisory board -- where 43% are people of colour and 52% are women. Nine of the 13 members of Biden's Covid-19 advisory board are people of colour and five of the members are women, according to the data.

Last week the transition team announced its agency review teams despite the General Services Administration not yet recognising Biden as the winner of the election. The teams consist of nearly 500 people, more than half of whom are women. About 40% of the team "represent communities historically underrepresented in the federal government," a transition official said, which includes people of colour, people who identify as LGBTQ+ and people with disabilities.

For months, the Biden-Harris transition has laid the groundwork for a Biden-Harris administration, and at the core of that work is an unrelenting commitment to diversity", said Ted Kaufman, co-Chair of the Biden-Harris transition. "As we continue working full-speed ahead to Inauguration, our diverse group of leaders and staff are reflective of America -- upholding -- President-elect Biden and Vice President-elect Harris' belief that through diverse voices we can develop and implement a policy vision to tackle our nation's toughest challenges."

The diversity figures mirror that of Biden's presidential campaign, which in September said 46% of its full time staff and 40% of its senior staff were people of colour. Women made up a greater share of Biden's campaign -- 59% -- than the current make-up of the transition team, according to the transition.

A transition official said the team provides weekly updates to its leadership to track the progress made in its diversity.

Biden has repeatedly promised that ensuring diversity in his administration and his cabinet will be a top priority.

"My administration's going to look like America, not just my staff, the administartion from the vice president straight down through cabinet members to major players within the White House, and the court." Biden said during a June townhall focusing on issues tied to the Asian American and Pacific Islanders communities. "Its going to be a reflection of who we are as a nation."
