Eco 572: Research methods in Demography The Page Model of Fertility by Age and Duration We apply Page's model of marital fertility by age and duration to study urban-rural differentials in Colombia, following essentially the procedures in Rodríguez and Clelland (1980). We will work with an extract from the 1976 WFS that has the dates of R's birth, first union and interview, the birth history, and type of place of residence. . use , clear (COSR02 extract) Events and Exposure We will focus on fertility in the three-years before the interview. A woman starts contributing events and exposure 3 years before the interview or when she enters a first union, whichever occurs later. We create a variable bot to mark the start of exposure . gen bot = v007-36 . replace bot = m012 if m012 > bot (2531 real changes made) . gen top = v007-1 . drop if bot >= top // no in-union exposure (2088 observations deleted) The next step is to count births in the window, occurring between bot and the month before the interview. The WFS coded the dates of birth of up to 24 children in variables called b012 b022 b032 ... b092 b102 b112 ... b242 . We use a loop with a local macro zj representing the zero- padded birth number to construct these variable names.

    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.
