  1. a Algorithm is based on a total score for children between 3 and 6 years: Total score = 0.2*education_score + 0.2*foreign background_score + 0.2*purchase power_2 + 0.4*caries risk (Maximum score = 3.0; minimum score = 1.0)
  2. b Statistics Sweden provided parish-level data on three socio-economic indicators: i) the proportion with post-secondary education among all residents; ii) the proportion of immigrants (more specifically, individuals born outside Sweden and individuals born in Sweden with both parents born outside Sweden) among all residents; and iii) the proportion of families with low purchasing power (according to Swedish standard) among all residing families with at least one child (<20 years old; family with the same residence address)
