    Data received as of 5/7/2024. N.J.A.C. 5:23-4.5 (d) requires municipalities to report to DCA monthly, information on each construction permit issued. Contains information about construction permits issued in New Jersey, including demolition permits. Data is collected from most, but not all municipalities that issue permits. It is processed and updated monthly. Data is purged from this dataset after 60 months have elapsed since the data was received. Accuracy of this data is not guaranteed, it may contain errors, and may not be complete. Data for permits issued in the immediate previous two months has not been reviewed. Note that this is the raw unaudited data, and may vary from the official published information in the monthly and annual Construction Reporter, as the official report contains corrected data, and the official report does not include updates received after the date of publication. We have no data for these municipalities: ALPHA WARREN 2102, ANDOVER BOROUGH SUSSEX 1901, LAKEHURST OCEAN 1513, NATIONAL PARK GLOUCESTER 0812, PINE BEACH OCEAN 1522, QUINTON SALEM 1711, VICTORY GARDENS MORRIS 1437, WINFIELD UNION 2021, WOODLYNNE CAMDEN 0437 Note: We've added Treasury Municipality Code to this dataset, and separated the Municipality Name in to Muni Name and Muni Type. Note 2: Questions on individual permit records should be directed to the office or agency which originally issued the permit. Note 3: This is raw data.

    NCHS - Drug Poisoning Mortality by County: United States

    data.cdc.gov | Last Updated 2022-03-29T21:27:25.000Z

    This dataset contains model-based county estimates for drug-poisoning mortality. Deaths are classified using the International Classification of Diseases, Tenth Revision (ICD–10). Drug-poisoning deaths are defined as having ICD–10 underlying cause-of-death codes X40–X44 (unintentional), X60–X64 (suicide), X85 (homicide), or Y10–Y14 (undetermined intent). Estimates are based on the National Vital Statistics System multiple cause-of-death mortality files (1). Age-adjusted death rates (deaths per 100,000 U.S. standard population for 2000) are calculated using the direct method. Populations used for computing death rates for 2011–2016 are postcensal estimates based on the 2010 U.S. census. Rates for census years are based on populations enumerated in the corresponding censuses. Rates for noncensus years before 2010 are revised using updated intercensal population estimates and may differ from rates previously published. Death rates for some states and years may be low due to a high number of unresolved pending cases or misclassification of ICD–10 codes for unintentional poisoning as R99, “Other ill-defined and unspecified causes of mortality” (2). For example, this issue is known to affect New Jersey in 2009 and West Virginia in 2005 and 2009 but also may affect other years and other states. Drug poisoning death rates may be underestimated in those instances. Smoothed county age-adjusted death rates (deaths per 100,000 population) were obtained according to methods described elsewhere (3–5). Briefly, two-stage hierarchical models were used to generate empirical Bayes estimates of county age-adjusted death rates due to drug poisoning for each year. These annual county-level estimates “borrow strength” across counties to generate stable estimates of death rates where data are sparse due to small population size (3,5). Estimates for 1999-2015 have been updated, and may differ slightly from previously published estimates. Differences are expected to be minimal, and may result from different county boundaries used in this release (see below) and from the inclusion of an additional year of data. Previously published estimates can be found here for comparison.(6) Estimates are unavailable for Broomfield County, Colorado, and Denali County, Alaska, before 2003 (7,8). Additionally, Clifton Forge County, Virginia only appears on the mortality files prior to 2003, while Bedford City, Virginia was added to Bedford County in 2015 and no longer appears in the mortality file in 2015. These counties were therefore merged with adjacent counties where necessary to create a consistent set of geographic units across the time period. County boundaries are largely consistent with the vintage 2005-2007 bridged-race population file geographies, with the modifications noted previously (7,8). REFERENCES 1.
