Like the other old villages, Janko Kala experienced a population decline in the LF1. Sector D has a population index value of 277 (5.0 ha), as opposed to 429 for the MF Sector C, an annual population growth rate of -0.08%. This is the same rate at which Chiripa (T-1) lost population in this period, suggesting that the two sites were subjected to similar sets of pressures and possibly tribute exactions.
