At the Kabupaten level, the average relative cash flow per worker is 74 million Rp (with 95% confidence limits of 70 to 78 million Rp), but the dispersion is high and the spatial heterogeneity among villages is considerable (Figure 18). In some villages, the added value per worker is less than 1 million Rp/year, while others produce more than 600 million Rp/year/worker. There is no clear explanation for the differences, as they are not obviously linked to either the industrial or spatial concentrations. The pattern probably reflects the existence of specialised businesses, scattered across the area. Further investigations are needed.
