Injury mortality rates among children and teenagers have been published for the United States,¹ Australia,² New Zealand,³ and England and Wales,⁴ all of them high income countries. No such statistics are available from middle or low income countries, where the injury picture is different.⁵ Table 1 summarizes injury mortality rates among children and teenagers in Mexico, a middle income country. We chose 1997 data because they are the most recent data available. We also present figures from 1993 for comparison (table 2). The cause specific mortality data are form the Health Ministry, through the Public Health National Institute, and are based on information reported on death certificates, collected by the National Institute for Statistics Geography and Information. To facilitate comparisons, we present our data in the same format as that published previously in Injury Prevention.^1–4 Injury mortality rates were calculated using linear projections from published census population (1990 and 1995) denominator data.
