In the United States, mathematics, as one of the specialties in the STEM field, is very popular with students studying in the United States. The United States is the country that has won the Fields Prize (one of the highest international awards in the field of mathematics, known as the Nobel Prize in mathematics) with the largest number of people, and has strong strength in mathematical research. According to the statistics of the Bureau of Labor Statistics (BLS), in May of 20021year, the median annual salary of mathematics-related occupations was $98,680, which was much higher than the median annual salary of all occupations in the United States of America of $45,760.

2. France

This country may be a bit unexpected. For a long time, France has been deeply rooted in people's hearts with the image of "luxury paradise", "tourist resort" and "romantic city".

But in fact, France's strength in mathematics should not be underestimated. Its mathematics has a long history, and many famous mathematicians such as Descartes, Fermat, Pascal, Legendre, Lagrange, Laplace, gaspard monge, Fourier, Poisson, Cauchy, Galois, joseph liouville, Hermite, Poincare and so on have been born. At present, there are nearly 4,000 mathematics researchers in France, which is one of the countries with the highest density of mathematicians in the world. Among the current 64 Fields Medal winners, France occupies 12 seats, perhaps less than the United States, but in terms of population ratio, it is definitely far ahead.
