“…I will assume that we can, in fact, reliably infer population growth from site numbers, while recognizing that there are problems with the use of recorded site numbers or components as a proxy measure of population growth (see Thompson and Turck, 2009 for a recent example of the use of site file data in population trend estimates; cf. Ramenofsky, 1987:14-31; also Raber, 2008;and Wyatt, 2003 for a discussion of Early Woodland populations in Pennsylvania). This hypothesis fails when we compare, period by period, rockshelter components to all site components (see Figures 1 and 2).…”
