Sajid Javid is right to argue against scrapping the Office for National Statistics. National studies have provided vital information to support decision-making.
For a real-time health system to be reliable and cost-effective, it has to rely on more than one test. The data sets are likely to be biased as it is not possible to know how many people are reporting negative results and how many are not testing. If we are to get reliable information about the prevalence of Covid, we need to keep studies such as the ONS and React to allow us to estimate infectiousness and the proportion of the population who are not sick.
The future health of the public will be put at risk if the system is disrupted. If important studies need to be scaled down, this can't be led by arbitrary cost-cutting targets, but should be led by statisticians to ensure reliable information. The president of the Royal Statistical Society is Sylvia Richardson.
We have a small favour to ask. We would like to thank you for trusting our journalism last year, and invite you to join the million-plus people in 180 countries who have recently taken the step to support us financially, keeping us open to all and fiercely independent. This support will support investigative work into offshore wealth, spyware, the 6 January insurrection, the corporate actors behind the climate crisis, and the abuses of Big Tech. The new year will hopefully herald a fresh sense of cautious optimism, and there is a lot for us to focus on in the next year, including the US elections, the fight for racial justice, and the World Cup. With no shareholders or billionaire owner, we can set our own agenda and provide trustworthy journalism that is free from commercial and political influence, offering a counterbalance to the spread of misinformation. We can investigate and challenge without fear or favour. Guardian journalism is free for everyone to read, even if they can't afford it. We believe in information equality. Greater numbers of people can keep track of global events, understand their impact on people and communities, and become inspired to take meaningful action. It is now a good time to join us. Our journalism is powered by every contribution and sustains our future. It only takes a minute to support the Guardian. Thank you.
