Hello all, I am trying to figure out how to construct several new variables without having to write a code for each one. Specifically, I want to calculate ratios for several variables. For instance, let's say I have:
df male1990 male1995 male2000 male2005 female1990 female1995 female2000 female2005 10 11 15 17 15 14 17 20 23 22 25 28 25 22 27 30 32 33 37 36 31 37 37 35 I want to calculate sex ratios for each of the years. Please note that this is an example. I want to calculate age-specific ratios for 5-year age groups, meaning that this will create a lot of variables. I am not well versed with looping functions and would appreciate it if someone provided some information and guidance as how to approach this. Thanks very much!
