There is a variable which isolates those that were born in 1988 and those with missing values (coded as 88). 85 | 487 3.08 41.93 86 | 526 3.33 45.26 87 | 583 3.69 48.95 88 | 650 4.12 53.07 89 | 525 3.32 56.39 90 | 722 4.57 60.96 91 | 607 3.84 64.81 92 | 610 3.86 68.67 93 | 682 4.32 72.99 94 | 692 4.38 77.37 95 | 700 4.43 81.80 96 | 711 4.50 86.30 97 | 724 4.58 90.89 98 | 638 4.04 94.93 99 | 801 5.07 100.00 ------------+----------------------------------- Total | 15,793 100.00 -----Original Message----- From: Nick Cox [mailto:n.j.cox@durham.ac.uk] Sent: 27 April 2004 12:28 To: statalist@hsphsun2.harvard.edu Subject: st: RE: RE: RE: RE: RE: creating age at first birth from birth history data I have a substantive query in return, fired by idle curiosity. In your data for -year- (below) there is a big peak in 1988. On another variable, it seems that "88" was used to code missing, as you excluded it from tabulation. Is it possible that the real 88s for -year- (i.e. born in 1988) have got mixed up with missings (coded 88) ? Nick n.j.cox@durham.ac.uk Henry DOCTOR > Perfect!
