The postcode lottery is denying girls equal access to sport.

Girls across the UK are missing out on an estimated 280 million hours of sport every year compared with boys. New research commissioned by Sky suggests that where a girl grows up can significantly shape her opportunity to be active.

The scale of the gender participation gap is troubling. Girls aged between 11 and 18 take part in an average of 84 fewer minutes of sport each week than boys.

But the national figure tells only part of the story.

Game Changing: How Sport Gives Every Girl a Better Chance, produced for Sky by research consultancy Public First, maps the gender participation gap across all 650 UK parliamentary constituencies. It reveals a stark postcode lottery.

In some constituencies, the difference between girls’ and boys’ participation is relatively small. In others, girls are missing out on more than two-and-a-half hours of sport every week.

The widest gaps are concentrated in parts of the West Midlands and the north-east, while constituencies in the south-west, north-west and Scotland generally perform better. Birmingham Perry Barr records the largest disparity, while Westmorland and Lonsdale has one of the smallest.

This is not simply a north-south divide. The research points instead to the importance of local conditions, including access to suitable facilities, personal safety, transport and the availability of welcoming opportunities.

Opportunity is shaped by place.

Girls living in towns and cities participate in almost 100 fewer minutes of sport each week than boys. In rural communities, the difference is closer to 75 minutes.

Urban communities may offer more facilities on paper, but proximity does not always mean accessibility. If girls do not feel safe travelling to a venue, cannot secure equal access to pitches or believe that a facility has been designed primarily for boys and men, the opportunity is not genuinely open to them.

The quality and availability of local sports provision also matter. In areas with the poorest provision, the gender participation gap is 46 per cent wider than in the best-served communities.

Girls from ethnic minority backgrounds face even greater disparities, demonstrating that gender cannot be considered in isolation from ethnicity, income, place and wider inequality. The report makes an important distinction: this is not simply a problem of girls lacking interest in sport.

Many want to be active but encounter cultural and structural barriers that gradually push them away. A lack of belonging sits at the heart of the issue.

Unequal access to facilities and school teams, limited visibility of female coaches and role models, concerns about safety and harassment, and persistent sexism all influence whether girls feel sport is a place for them.

More than one in three girls has experienced sexist comments while participating in sport. Among older teenage girls, that rises to more than four in 10. Almost one in four has experienced sexual comments. These are not minor inconveniences. They shape confidence, enjoyment and the decision to keep participating.

Visibility matters—but it must lead to opportunity.

More than half of girls say that seeing elite female athletes inspires them to take part in sport.

The continued growth and visibility of women’s sport therefore matters enormously. Athletes such as Alessia Russo can challenge perceptions, create ambition and show girls what is possible.

A girl may watch women competing on the biggest stages and feel inspired, only to find that her local club has no suitable team, the available session feels unwelcoming or the nearest safe opportunity is too difficult or expensive to reach.

Visibility must be matched by accessible opportunities in schools, clubs, leisure facilities and community settings.

That means more female coaches and leaders, beginner-friendly programmes, fair access to facilities and playing time, appropriate changing spaces and environments in which sexist behaviour is challenged rather than tolerated.

The cost of inaction.

Closing the participation gap would not only improve the lives of millions of girls. Public First estimates that it could generate approximately £570 million in productivity gains each year and save the NHS £73 million annually through improved health.

By 2035, the cumulative economic and health benefit could reach £6.5 billion.

Those figures strengthen the case for investment, but the argument should not be reduced to economics alone.

Every girl should have the opportunity to experience the confidence, friendships, enjoyment and physical and mental health benefits that sport can provide. Access should not depend on her postcode, background or whether local provision has been designed with her needs in mind.

Sky’s Game Changing campaign is calling on government, schools, sports organisations and local communities to work together to improve girls’ access to sport. The campaign includes partnerships with Alessia Russo and the charity Goals 4 Girls, which supports young women through football and education.

The research presents a clear challenge to the sport and physical activity sector.

Building more facilities will not, by itself, solve the problem. We must understand who feels able to use them, who feels welcome when they arrive and whose needs have shaped the programmes being delivered.

Safe spaces matter. Representation matters. Female leadership matters. Affordability, accessibility and a sense of belonging matter. If girls are missing out on 280 million hours of sport every year, this is not a marginal participation issue. It is a systemic failure—and one that requires coordinated national ambition supported by meaningful action in every community.

The postcode lottery must end. Every girl, wherever she lives, deserves an equal chance to be active.
