I wonder if the following sentneces which discuss the marriage are correct or not.
1.For the past 10 years, the number of men who first married decreased around 50 percent.( 1988 42. 6 per 1000 -->1999, 26.5)
2. Similarility, the number of remarriages for both men and women decreased. Compared women, the number of men who enter the seconed marriage decrease around 40 percent.
Meanwhile 26.5/42.6 = 62.2%, approximately 60%.
The first time marriage rate dropped by approximately 38%, to approximately 60% of the rate for the previous ten-year period.(A drop from 100 to 80 is a drop by 20%, to 80% of the original.)
Perhaps this discrepancy could be explained by a total population decrease, in which case the latest 26.5 per 1000 figure would be larger in proportion in total population - in which case approximately 50% (of total male population, but not per 1000 men) might be right.
Disclaimer: I'm not a statistician.
Neither am I a statistician and I wasn't paying too much attention to the actual figures - more the phrasing. I had in my mind the IELTS task 1.
I just saw 26.5 and 42.6 and decided that the writer was near enough with the 50% drop (a sort of 2+2=5), but you are closer with the 38% ie just over two-thirds. I am not sure that I follow the 'drop by 20% to 80% of the original' argument: was that an illustration of the point perhaps?
