Not of an individual, but of a country.
This is a “Global Creativity Index” for 2015 (60 page pdf here) — the creativity of countries, ranked. How do they measure creativity? The “three Ts”:
- technology: basically, how much the country spends on research & development and innovation
- talent: “the share of the workforce in the creative class and the share of adults with higher education”
- tolerance: “openness to ethnic and religious minorities and gay and lesbian people”
Japan is ranked #2 (behind South Korea) in the technology index, #58 in the talent index, and #39 in the tolerance index. The researchers ranked a total of 139 countries.
There’s some interesting data here, and a lot of themes you could use as research topics.
