The annual population growth rate in the LF1 decreases from the MF rate of 0.13% (Table 6.3) to 0.08% (Table 7.2). This is simply a continuation of a trend already observed in the MF. The value of 0.08% annual growth is comparable to Hassan's estimate of 0.1% annual population growth for preindustrial agrarian societies.
It is possible that the decrease in the population growth rate in the LF1 is no more than an analytical artifact. Since the population in the LF1 was becoming increasingly concentrated in larger sites (see below), and since larger sites are probably slightly underrepresented in my population estimates (see Chapter 4) the decrease in the growth rate could be an analytical artifact. Whatever the case, the population growth rate was roughly comparable to that of the MF and in line with expectations derived from cross-cultural comparisons. Thus, there is no reason to suspect that either immigration or outmigration were taking place at significant rates.
