1 Eco572 – Research Methods in Demography G. Rodríguez- Spring 2006 Problem Set 1 Due March 1, 2006 [1] World Population (a) What's the world population today? How fast is it growing? (Document your sources.) (b) The world population reached 6 billion sometime in 1999. When will it reach 12 billion at the current rate of growth? (Note: doubling time will get you only partial credit; as we are in 2006, not 1999.) (c) Describe a path for the rate of growth that will postpone reaching 12 billion until the end of the century (on Dec 31, 2100). [2] Standardization I used an extract from the 1998 DDHS survey for Kenya to tabulate current contraceptive use by age and type of place of residence. The table below shows counts of women and current users of contraception in each age group. We are interested in the percent currently using any method, also known as the contraceptive prevalence rate. Urban Rural Age Group N Users N Users 15-19 298 37 1451 88 20-24 332 116 1020 281 25-29 267 132 926 370 30-34 185 103 714 299 35-39 162 73 782 343 40-44 69 37 556 213 45-49 68 17 452 119 (a) Compute crude and standardized contraceptive prevalence rates using (i) the unweighted average of urban and rural as the standard, (ii) the overall age distribution as the standard.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
