The creative industry is becoming an increasingly important factor of modern post-industrial knowledge societies. It is defined as a new concept of merging art, media and design in 12 sectors, linked by cultural and creative innovations, new ventures and risks in business, and such a concept is very important for research because it creates a concept for the new economy. In order to explore the creative industry in a particular area, it is necessary to collect data. One of the ways of researching and measuring the creative industry is secondary data, which is already collected and known from earlier than primary data. Researchers using secondary data are at an advantage over researchers who ignore it. The paper describes the pillars of the creative industry measurement as a starting point for its understanding, and there are three levels of measurement: the contribution of the creative industry to the total gross domestic product of the Croatian economy, employment in the creative industry, and entrepreneurship that is closely related to the creative industry because they are innovative. Meeting the challenges and taking risks is crucial both in the creative industry and in entrepreneurship. The definitions of the creative industry have also been expressed and are divided according to country and geographical location and administrative understanding of the industry and its sectors. As far as Croatia is concerned, the creative industry should be further emphasized and given importance and emphasis, which means that the younger population should be encouraged to become involved.
