Statisticians come together with a shared vision to secure trusted data

“Data are critically important for everyone,” says Stefan Schweinfest, Director of UN DESA’s Statistics Division. “All the decisions that you take in your life, you're basing them on data,” he stressed, as we spoke on the important work of the UN Statistical Commission. On 4-7 March 2025, some 600 statisticians from across the world will come together at UN Headquarters in New York to ensure better data, better lives. 

From everyday choices – what clothes to wear based on temperature data; or what route to take when commuting; to informing decisions that matter for improving peoples’ lives – it is all based on data. “You need to know how many people you have in your country and what groups you have to take particular care of,” Mr. Schweinfest said, explaining the importance of data in managing services like health care and education.

Commission to focus on two big topics this year

A veteran in the statistical community, we met Mr. Schweinfest on the eve of the Commission’s 56th session. He shared that two big topics will be addressed this year - the 2025 Systems of National Accounts, and the 2030 World Population and Housing Census Programme. 

“We will adopt a new system of national accounts,” he explained, describing its most recognized element, the Gross Domestic Product (GDP). “The system of national accounts is the guidebook to measure your economy the same way, whether you are in Mongolia or in Paraguay,” he said, noting that using the same statistical language enables countries to successfully exchange information and experiences. 

“Every decade, the United Nations calls and declares a census round,” Mr. Schweinfest continued, describing the process of countries committing to counting their people. The census will help the international community better understand where people live and what their living conditions are, which later forms the basis for policy advice and decisions. “At the end, we will have good numbers for all of the countries and the whole world,” he explained.

Combining census data with economic trends

Mr. Schweinfest also outlined the possibilities when pairing census data with economic trends.  

“With the system of national accounts, you understand where income is generated, which activities generate income and how the income is distributed in your population,” he said. He also described how this process can help countries intervene when needed to make sure that the well-being of people as well as the environment are protected.

Mr. Schweinfest also emphasized that the work on going beyond GDP to make nature count, is part of ongoing efforts in the statistical community, integrating economic and environmental accounting. 

How data helps advance sustainable development

“I'm very proud of the statistical community,” Mr. Schweinfest said, as we discussed the role the statistical community plays in advancing sustainable development and the Sustainable Development Goals (SDGs).

“I think the deliberate decision in 2015 was to make the development agenda an accountability framework. That's why it was structured in goals, targets and indicators. And whilst the goals and targets obviously come from the political sphere, the indicators were really managed in this room,” he said, describing how these 240 indicators help the international community measure and assess SDG progress every year.  

A professional community of solidarity, with a shared vision

As the UN Statistical Commission comes together this month, it will also discuss other important matters including the Fundamental Principles of Official Statistics, SDG indicators, environment and climate change statistics, environmental-economic accounting, household surveys, economic statistics, and many more topics. 

Mr. Schweinfest described the privilege he feels, being part of the Commission’s work. “To look at this room full of people who've come to […] discuss these topics, that is always a fantastic feeling,” he said. “I look at us as a community of solidarity, a professional community with a shared vision,” he continued, stressing that it is all about ensuring data quality and reliability. 

He also looked back at some major developments of the Commission’s work over the past 36 years. “It is a much bigger Commission,” he explained, sharing how there are many more countries participating. “Nowadays we have sessions with 120 and 140 countries […]. It has also become much bigger and broader in terms of topics,” he said, highlighting integrated economic and environmental statistics, as well as human rights and governance statistics, as some of the new areas covered by the Commission. 

Mr. Schweinfest also highlighted that there are more interesting data sources these days, including private sector data, big data, citizen reported data, geographical and geospatial data.

As we wrapped up our interview in Conference Room 4 at UN Headquarters, or the Commission’s "natural habitat", as Mr. Schweinfest described it, he concluded, “I've always considered that this is the best job in the universe.”
