*New York City has been reporting chlamydia cases since 1984. The State of New York, with the exception of New York City, initiated chlamydia reporting during the year 2000. The number of chlamydia cases reported from 1998-2000 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 (Reporting of Chlamydia Cases).

Rates exclude population of cities that did not report. NR=No report
