Do you know where the college entrance examination is the hardest and which year is the most difficult? I'm using Python data to analyze

Code:

This is since 1977 to resume the college entrance examination and the 2017 entrance examination and admission data. Part of the data is omitted from the space limit. In order to display visually, the rate of admission has been changed on a scale. After 2000, the most difficult (the lowest admission rate) of the first year of college entrance examination is 2007, the admission rate is only 56%, but this is already more than in the 890 's 20% or 30% admission rate is much higher. On the whole, it's getting easier to get to college. On the data, 03 is not as bad as it might seem.

As can be seen from the figure, the number of applicants each year also has a small fluctuation. I went to find the demographic data of the past year, compared with the number of candidates:

Compared with the twenty or thirty-year-old increase in education penetration and the slowing population growth, more and more people are receiving higher education. But it can be inferred from the scale that college is still not something that everyone can enjoy.

Look at the distribution of time, then the region? Compared with the overall admission rate, people are more controversial than the difference between the different regions before the college entrance examination.

First look at the following 2018 years of registration in each province:

Code:

data_prov_ad = [(‘湖南‘, 11.2), (‘江西‘, 10.4), (‘安徽‘, 14.2), ..., (‘浙江‘, 14)]geo = Map("2017各省一本录取率")attr, value = geo.cast(data_prov_ad)geo.add("", attr, value, visual_range=[8, 20], is_visualmap=True, is_map_symbol_show=False)geo.render()

The hardest three regions: Henan 7.8%, Guangxi 8.44%, Shanxi 9.8%

The highest acceptance rate in three regions: Beijing 30.5%, Tianjin 24.1%, Shanghai 21.8%

(Missing Hainan data)

And Jiangsu last year's 12.1% is not in line Top10.

From a personal point of view, do not cling to absolute fairness, but from the perspective of society as a whole, we should give everyone a more equal opportunity. It is believed that in the near future, the curve of enrolment and acceptance will be more and more close, and the color of the admission rate distribution chart is becoming more and more consistent.

Source code can be entered into the group: 125240963 can get it
