Annual death data have been tabulated by sex, race/ethnicity, age, and underlying cause of death for residents of selected municipalities in New Jersey .
Geographic data quality:
Mortality data are presented for the 341 municipalities in which the quality of death certificate data on residence is sufficient. Death data for the remaining 225 municipalities believed to have a relatively high level of uncertainty in allocation of municipality are included in the respective “balance of county” group. For more information on the problem of assignment of municipality of residence on vital records, go to: www.nj.gov/health/chs/releasable.htm.
Data source change:
The Center for Health Statistics (CHS) used multiple cause of death (MCD) files compiled by the National Center for Health Statistics (NCHS) for the 1999-2002 New Jersey Health Statistics reports. The single cause of death (SCD) file compiled internally was used to produce the mortality tables in New Jersey Health Statistics, 2003. For the updated 1999-2003 Municipality-Level Deaths by Selected Characteristics tables above, linked SCD-MCD files were used. There are several differences between the SCD and MCD files and the linked files offer the best aspects of each:
- The MCD file does not separately code residence information for municipalities with populations less than 10,000. Therefore, residence information from the SCD was used.
- The MCD file yields full information on resident deaths occurring out of state, while the SCD file contains full information from some states but limited information from other states and New York City . Therefore age, race, ethnicity, sex, and cause of death data from the MCD files were used.
- Missing race, sex, and residence data are imputed on the MCD file (missing data are assigned a value based on an algorithm), while the SCD file leaves them blank.
- Any records sent to the state registrar after NCHS’s cut-off date for receipt of records will not be in the MCD file. Additionally, any duplicate records identified by DOH after NCHS’s cut-off date will not be removed from the MCD file. However, these numbers are thought to be negligible. Occasionally, records for New Jersey resident deaths that occurred out of state are not sent to the state registrar yet are included in the MCD file. These numbers are also thought to be negligible. The linked files capture all records from the SCD and MCD files.
Change in race/ethnicity reporting :
In 2005, CHS began presenting death data for the following race/ethnicity groups: White (non-Hispanic), Black (non-Hispanic), Hispanic (of any race), Asian/Pacific Islander (non-Hispanic), and Other Races (non-Hispanic). In the past, death data were usually only presented for White, Black, and All Other Races, regardless of Hispanic ethnicity. The data in the above tables have been updated to correspond to the race/ethnicity groups currently in use. For detailed discussions on the quality of race and ethnicity reporting on death certificates, go to www.nj.gov/health/chs/asian/asianmort89-98.htm and www.nj.gov/health/chs/hispanic/hispmort89-98.htm.
Changes in cause of death classification beginning in 1999:
The classification of causes of death changed in 1999. The International Classification of Diseases (ICD) is a product of the World Health Organization and is used worldwide. The United States adopted the Tenth Revision of the ICD (ICD-10) in 1999. The revision not only affects the codes and names assigned to causes of death, it also affects the rules for selecting the underlying cause of death and the grouping of causes for tabulation and selection of leading causes of death. Because of this, 1999-2003 cause of death data are not directly comparable to data from previous years. To make 1994-1998 deaths coded under the ninth revision (ICD-9) comparable to current data, NCHS has computed comparability ratios for major causes of death. When applied to 1994-1998 deaths coded in accordance with ICD-9, the comparability ratios allow for trend analysis. NCHS does not recommend using these ratios with data prior to 1994.
