=New York City has been reporting chlamydia cases since 1984. However, the State of New York, with the exception of New York City, initiated chlamydia reporting during the year 2000. As a result, the number of chlamydia cases reported by the state of New York (including the cities of Buffalo, Rochester and Yonkers) may be incomplete and the rate for New York State is underestimated. See Appendix.

1Includes cases reported by Washington, D.C., and rates exclude population of states that did not report.

NOTE: Cases and rates underestimated in some areas because of under-reporting or non-reporting by gender.
