This paper deals with NPEAJ for 100 years covering the period of 1961-2060. We
examine the historical data of NPEAJ for the period 1961-2004. In particular, we build a forecast
model based on the NPEAJ data of 1983-2004. To these historical data, we fit a Fisher-Pry Sshaped
model. The bound for the model is estimated to be 790. With the model obtained, we
forecast NPEAJ for the period 2005-2060.
