There are no “official” classifications, so I’ll feel free to make one up:
Natural Entrepreneurs are those who were born that way and simply can’t help themselves. It’s like being born left-handed or with webbed feet. The percentage of these in the population is around 1%, regardless of location.
Self-made Entrepreneurs are those who were not born that way but have nevertheless proactively started their own ventures. In developed countries the percentage of these in the population is [All Founders - Natural Entrepreneurs], or roughly 2–3%, and in developing countries about twice that.
Survival Entrepreneurs are those people who have founded a business out of the necessity to put food on the table for themselves and their families in a society where there are no other options. The percentage of these in developed countries is near zero, whereas in developing counties it can be as high as 30–40%.
Aspirational Entrepreneurs (sometimes referred to unkindly as “wantrepreneurs”) are those who are enamored of the concept of entrepreneurship, spend lots of time reading, meeting, thinking and talking about entrepreneurship, and call themselves entrepreneurs, but never actually get around to founding a venture. These folks consist of 4–6% of the population in developed countries, and near zero in developing countries.
