Agreement between first year of life exposures assigned to address at birth (from the birth certificate) vs address at diagnosis (from the CCR) among cases born 1998–2011 and diagnosed at age 1–5 years, using a 2000 m buffer.

^aSpearman correlation coefficients were calculated using continuous exposure estimates in child’s first year of life

^bKappa statistics were calculated using binary exposure indicators for child’s first year of life

^cNon-movers (D ≤ 100 m) had almost perfect correlation and therefore are not shown here
