Note: ABCD, Amsterdam Born Children and their Development; ${\mathrm{NO}}_2$, nitrogen dioxide; ${\mathrm{PM}}_{10}$, particulate matter less than $10\mathrm{\mu }\mathrm{m}$ in aerodynamic diameter; SEP, socioeconomic position; VIIRS-DNB, Visible and Infrared Imaging Radiometer Suite Day/Night band.

^aAir pollutants ${\mathrm{NO}}_2$ and ${\mathrm{PM}}_{10}$ are modeled average values in micrograms per cubic meter.

^bGreen buffer corresponds to the amount of square meters of green in a buffer of 100 and $1000\mathrm{m}$ around the place of residence, respectively, based on vegetation cover indicated on the Dutch cadastral map TOP10.

^cDegree of rurality, population density and area-level SEP derived from the smallest area unit (“buurt”) by Statistics Netherlands.

^dDegree of rurality ranges from 1 (very urban) to 5 (rural).

^ePopulation density refers to number of inhabitants per square kilometer.

^fArea SEP refers to the percentage of the population with low income.
