Study title: Gross fixed capital formation by main asset type (nama_10_an6)

In addition to contributing to the expenditure approach to GDP, data on gross fixed capital formation is key in compiling capital stocks data and balance sheets published in Eurobase tables nama_10_nfa_st and nama_10_nfa_bs respectively. It has therefore many indirect uses, e.g. for the analysis of productivity developments and growth accounts.

Gross fixed capital formation consists of resident producers’ investments, deducting disposals, in fixed assets during a given period. It also includes certain additions to the value of non-produced assets realized by producers or institutional units.

Countries use many sources to compile their national accounts, among them administrative data from government, population censuses, business surveys, external trade and balance of payments statistics, and household surveys. Sources vary from country to country and may cover a large set of economic, social, financial and environmental items.

1. We collect data directly from official government sources, most often via an API provided by the relevant statistical office. For this purpose, we use proprietary algorithms that retrieve and aggregate all information into our database.
2. We standardize and clean the data for better analysis and readability. We remove unnecessary elements and adjust the structure to a unified format, which ensures consistency between different data sets. This enables visual interpretation of statistics as well as comparative analysis — both by humans and analytical systems (including artificial intelligence).
3. We verify the information and design an interactive chart. We aim to make the information transparent and easy to understand, so we start with a presentation of general indicators that serve as a starting point for deeper data exploration. The user can then dive into the details using interactive chart features. We do not interfere with the content or meaning of the data — our role is solely to organize and facilitate access to the information.
4. We create metadata and translate the chart into other languages. Each chart is supplemented with sources, survey details, and other information provided by the data supplier. We also use our own AI models to generate a short summary of the chart. Finally, we translate the content and publish the charts on 47 international Content Writer websites to share valuable information with the world.
5. We regularly update and expand the data. Our scripts "listen" to data providers’ websites and retrieve the latest information as soon as updates appear. We then recreate the chart summary to reflect recent changes. The update is published, and interested users are informed about the current trend.

The data is processed by Content Writer — a limited liability company based in Poland — as part of the independent WorldIndex project. The initiative’s goal is to provide free access to current public data for analyzing trends and better understanding the world.

We also offer commercial access to the WorldIndex API, which provides direct access to data via an API. This allows companies, organizations, and individual users to integrate a real-time information stream into their applications, analytical systems, or AI models.
