The article traces the onset of the fertility transition (a widespread trend in Asia) in Kathmandu. This paper analyses the onset of the fertility transition using data from a survey carried out in Kathmandu in 1997. The analysis uses the index of marital fertility control (m) and parity progression ratios to document the onset of fertility changes. The results show that women tend to have children shortly after marriage. Nevertheless, there is evidence of a transition toward two and three child families. Additionally, as educational attainment rises, women's fertility declines. (Rajeev Ranjan Singh 2007-10-28)
