Article by Lucila Pinto, Ehsan Masood, and Subhra Priyadarshini: “Uncertainty.”, “Loss of trust.”, “Definitely a crisis.” These are some of the ways in which researchers describe the state of affairs for government data in many countries.
“There is a new type of politics that is undermining the credibility of official statistics,” says João Pedro Azevedo, chief statistician for the United Nations children’s agency UNICEF in New York City.
Official statistics are data collected and validated by both national statistical agencies and international organizations. Nearly every country has an agency for official statistics. They collect information and organize it into statistics about myriad aspects of life, including what people earn, how many individuals are employed, how well children perform in school, the quality of nutrition, how long patients have to wait for an operation, levels of air pollution and increases to average temperatures.
National agencies collect data through surveys and from secondary sources. These data sets are used by governments to inform policy, by businesses to plan for the future, and by researchers and advocacy organizations. Official statistics, such as those measuring nations’ gross domestic product (GDP), are also the foundation for monitoring progress towards the 17 UN Sustainable Development Goals, the world’s plan to end poverty and achieve environmental sustainability.
“Official statistics are like the backbone of a nation’s data infrastructure,” says Steve Pierson, director of science policy at the American Statistical Association (ASA) in Washington DC. “Just like any other infrastructure — roads, bridges and highways — they cannot fail.”
People who work with or study official statistics say that they have never experienced a period similar to today’s situation. Those who call the current state a crisis think it has been triggered by an accumulation of overlapping factors. These include falling response rates to national surveys, cuts to funding and, in some cases, government interference.
Although funded by governments, national statistics offices are expected to operate independently of politicians, not least so that they are free to report the data as measured — much as academic research operates at arm’s length from its public-funding bodies. Moreover, rules established by an assembly of the world’s national statisticians and endorsed by the UN require that some data sets meet international standards, which state that official statistics should be accurate, impartial, trustworthy and grounded in evidence.
Although there is a history of inappropriate government involvement in the collection and reporting of national statistics (A. V. Georgiou Stat. J. IAOS 37, 85–105; 2021), there is a record of statistics agencies calling out the misuse of such data, too. But researchers worry that this might not be the case in future. “I fear that it is becoming harder for official statisticians to do their jobs,” says Diane Coyle, research director at the Bennett School of Public Policy at the University of Cambridge, UK.
