Partition of the net change between risk, structure and size in lung cancer incidence from Tarragona and Girona. 2000–2004 vs. 1995–1999: (I) Difference in the crude rate (number of lung cancer cases per 100,000 person-years) between 1995–1999 respect to 2000–2004 among men (A.1) and among women (A.2); (II) Difference in the absolute number of lung cancer cases between 1995–1999 respect to 2000–2004 among men (B.1) and among women (B.2). (Note that differences in the number of cases are partitioned into those due to risk and those due to population structure and population size.
