How can accurate economic data guide better policy-making in the global economy? What are the key economic indicators and key application of economic data?
Economic data: What does it mean?
Economic data are facts and figures that describe how an economy is working, either now or in the past. These data are often shown in a time-series format, meaning they cover more than one time period (for example, the monthly unemployment rate over the past five years). They can also appear as cross-sectional data, which show different aspects of the economy at one point in time (such as household income and spending levels in a given year).
Economic data may come from surveys of individuals and businesses or may be grouped into sectors and industries, either within a single country or at an international level. When these data are organised into tables, they form a data set.
The process of collecting, measuring, analysing, and publishing these data involves economic and statistical methods. The term ‘economic statistics’ can also refer to official statistics produced by organisations such as government statistical offices, central banks, and international groups like the United Nations, the European Union, and the OECD.
Economic data provide factual evidence for research in economics, whether for simple descriptions or for complex statistical analysis (econometrics). Data archives are also important for checking past research results and helping policymakers make decisions about economic policies.
How can accurate economic data guide better policy-making in the global economy?
Economic data for a country are often collected and organised following the rules of national accounting. Examples of such data include:
- Gross National Product (GNP) and its different parts
- Gross National Expenditure (GNE)
- Gross National Income (GNI)
- National wealth and capital stock
These data may be expressed in nominal values (money amounts without considering inflation) or real values (adjusted for inflation). Other key economic indicators include measures of economic output, trade, jobs, business confidence, prices, and financial statistics like money supply and interest rates.
At the international level, there are many data series covering topics such as global trade, financial flows between countries, direct investment, and exchange rates.
For time-series data, information may be measured and reported at different intervals, such as hourly, daily, monthly, quarterly, or yearly. In some cases, seasonal adjustments are made to remove changes caused by predictable events, like holiday sales or seasonal unemployment trends.
Within a country, economic data are usually produced by government agencies or central banks. International economic statistics are compiled by global organisations like the International Monetary Fund (IMF) and the Bank for International Settlements (BIS).
Some economic studies also produce their own data. For example, in experimental economics, researchers conduct experiments to gather new information instead of using existing data. Designed experiments are often more reliable than observational studies, which rely on pre-collected data.
However, in many cases, economists cannot fully control the environment they are studying, so they use observational data or quasi-experiments instead. These data are then analysed using statistical tools (econometrics).
Economic Data analysis
There are many ways to analyse economic data. Some common methods include:
- Time-series analysis, which looks at trends over time
- Multiple regression, which examines how different factors are related
- Box–Jenkins analysis, a method for predicting future values
- Seasonality analysis, which looks at recurring patterns in data
Analysis may focus on one type of data (univariate analysis) or multiple types at once (multivariate analysis). Experts such as econometricians, economic statisticians, and financial analysts create models to explain past trends and predict future events like demand, prices, and employment levels.
Some models focus on small parts of an economy (microeconomics), while others examine the economy as a whole (macroeconomics). Economists also use special techniques to correct errors in data and fill in missing information, ensuring their predictions are more accurate.
Types of Economic Data
There are several categories of economic data that are commonly used to assess the health of an economy. These include:
1. Gross Domestic Product (GDP)
GDP is one of the most widely used measures of economic activity. It represents the total value of all goods and services produced within a country in a given period. GDP is often used to assess the overall economic performance of a nation and to compare the economic strength of different countries. It can be measured in three ways: the production approach, the income approach, and the expenditure approach. For instance, the UK’s GDP was estimated at £2.27 trillion in 2023, making it the sixth-largest global economy.
2. Unemployment Rate
The unemployment rate measures the proportion of the workforce that is currently unemployed and actively seeking work. It is an essential indicator of labour market conditions and economic health. High unemployment rates generally signal economic distress, while low rates may suggest a healthy and growing economy. A rising unemployment rate can signal economic distress, while a declining rate may indicate economic improvement. In the UK, the unemployment rate increased to 4.4% in December 2024, influenced by recent fiscal policies.
3. Inflation Rate
Inflation is the rate at which the general level of prices for goods and services is rising, eroding purchasing power. It is commonly measured using indices such as the Consumer Price Index (CPI) or the Producer Price Index (PPI). Inflation data is crucial for central banks in their decision-making, as they aim to maintain price stability in the economy. The Consumer Price Index (CPI) is commonly used to track inflation. In India, the inflation rate was 6.7% in 2022, reflecting the increase in consumer prices.
4. Interest Rates
Interest rates, particularly the rates set by central banks, are vital to the functioning of an economy. They influence borrowing and lending activities, impacting everything from consumer spending to business investments. Central banks adjust interest rates in response to economic conditions, typically lowering them to stimulate economic growth or raising them to combat inflation. The Bank of England’s policy rate was 4.75% as of January 2025, the highest among major developed countries.
5. Trade Data
Trade data includes information on exports, imports, and the balance of trade (the difference between exports and imports). It is a critical component in understanding the global competitiveness of an economy and the flow of goods and services across borders. Trade data is often used to evaluate the economic relationships between countries. India’s exports were valued at $776.68 billion in the fiscal year 2023–24, highlighting its significant role in international trade.
6. Consumer Confidence and Business Sentiment
Surveys measuring consumer confidence and business sentiment reflect how individuals and firms feel about the future state of the economy. These measures are particularly useful for understanding potential future consumer spending and business investments, which can drive economic growth.
7. Industrial Production
Industrial production data covers the output of factories, mines, and utilities. It is an important measure of economic activity in the manufacturing sector. A rise in industrial production often signals economic expansion, while a decline may indicate a slowdown.
8. Retail Sales and Consumer Spending
Consumer spending accounts for a significant portion of economic activity in many countries. Retail sales data provides insights into how much consumers are spending on goods and services, and can be used to gauge overall consumer confidence. Rising retail sales are generally a positive sign for an economy, while declining sales may indicate weaker demand.
How economic data is collected
Economic data is gathered from many different sources, including government surveys, business reports, and international organisations. Governments usually collect data through surveys like census surveys, household income and spending surveys, and labour force surveys. They also use administrative records, such as tax returns and customs reports. For example, the UK’s Office for National Statistics (ONS) provides a lot of detailed economic data.
Apart from government sources, private research firms and economic analysts also play an important role in collecting and sharing economic data. They often gather statistics from industry reports, market surveys, and their own research to offer more specific insights into certain industries or areas.
International organisations such as the International Monetary Fund (IMF) and the World Bank also gather and share economic data for countries all over the world. For example, data about India’s economy can be found on the World Bank’s Open Data portal. These organisations often provide global economic indicators, which help compare different countries and track economic trends over time.
How is economic data used?
Economic data is used by different people and organisations for various purposes. Governments use this data to create fiscal and monetary policies, make decisions about taxes, public spending, and interest rates, and to check how successful their policies are. For example, if the economy is growing too fast and causing high inflation, central banks might raise interest rates to try to control the inflation.
Businesses use economic data to help make decisions about investments, hiring, production, and pricing. For example, a company might look at changes in consumer spending and industrial production when deciding if it should expand its production. Economic data also helps businesses predict how much demand there will be for their products and services.
Investors use economic data to help with their investment choices. They look at important factors like GDP growth, inflation, and unemployment rates to understand the economic situation and make decisions about where to invest. Stock markets are very sensitive to economic data, as the overall economy affects how well companies and industries will do.
Final thoughts
Economic data is an important tool for understanding how well an economy is doing and making well-informed decisions. It helps to understand key areas such as economic growth, inflation, employment, and trade. By studying and interpreting economic data, policymakers, businesses, and investors can better handle the complexities of the economy.
Even though economic data is very useful, it is important to be careful when using it. The accuracy, timeliness, and context of the data all play a part in how useful it is. Therefore, having a clear understanding of economic data is necessary for interpreting the information it provides and making decisions that will shape the future of economies.
