The percentage of entrepreneurship in Indonesia has not reached two percent of the whole population. This is proven by the survey result of Global Entrepreneurship Monitor (GEM) which shows that, out of the total population of two hundred fifty million people, there is only 1.65% entrepreneur in Indonesia; this figure is still below other ASEAN countries. Nevertheless, the survey result says the perceived opportunity in Indonesia is rather high with 47% and the proportion of perceived opportunity between man (51%) and woman (49%) is similar. This shows that Indonesian people have high intention to become an entrepreneur. There are many businesses that grow from different generation backgrounds. Based on the generation theory, there are five generation groups which are categorized based on their birth cohort: Mature Generation (1925 - 1945), Boom Generation (1946 - 1964), Generation X (1965 - 1980) Millennial Generation (1981 - 2000), and Generation Z (2001 - present). Previous researches have investigated the trend and characteristic of generations and entrepreneurial intention on a certain group. The objective of this research is to find out the trend of entrepreneurial intention on generation X, millennial and Z based on the priority and perception on the need of achievement, self-efficacy, instrument readiness, demography and interest. The main objective of this research is to investigate the difference of entrepreneurial intention on the different generations. In the future, research will be developed to be applicable. Data were collected using questionnaire distribution regarding entrepreneurial intention on each generation with purposive sampling method and the collected data then analyzed using difference test.
