A Critical Review of Rural Poverty Literature: Is There Truly a Rural Effect?

Abstract: Poverty rates are highest in the most urban and most rural areas of the United States and are higher in nonmetropolitan than metropolitan areas. Yet perhaps because only one-fifth of the nation's 3...

On the Urban Agglomeration and Economic Efficiency

Abstract: It is often argued that today's large metropolitan areas have exceeded the "optimal" size and, therefore, development efforts should be directed toward smaller urban centers.1 This argument is frequently based on the proposition that the economic return from investment, either private, public, or both, in large metropolitan areas is less than that in mediumand small-size urban centers. The purposes of this paper are (1) to demonstrate that this proposition cannot be supported by any available empirical analysis and that, in terms of economic efficiency, even the largest metropolitan area in the world is likely to be less than the "optimal" size; and (2) to point out that there is a legitimate objective for pursuing a decentralization policy for urbanization, that is, interregional equity, whereas in practice a decentralization policy is frequently proposed and undertaken for economic efficiency, an objective which this policy seems to affect adversely rather than favorably. Many writers have observed that the currently large metropolitan areas already have excessive population concentration. However, their assertions are rarely consistent with an economic efficiency criterion in the sense of increasing a country's total income. If they are made on the economic ground, they are not based on a systematic quantitative analysis but on either visual impressions or partial quantitative data. Only recently, sufficient quantitative data have become available to make a fairly strong

Illicit Drug Use, Illicit Drug Use Disorders, and Drug Overdose Deaths in Metropolitan and Nonmetropolitan Areas - United States.

Abstract: PROBLEM/CONDITION Drug overdoses are a leading cause of injury death in the United States, resulting in approximately 52,000 deaths in 2015. Understanding differences in illicit drug use, illicit drug use disorders, and overall drug overdose deaths in metropolitan and nonmetropolitan areas is important for informing public health programs, interventions, and policies. REPORTING PERIOD Illicit drug use and drug use disorders during 2003-2014, and drug overdose deaths during 1999-2015. DESCRIPTION OF DATA The National Survey of Drug Use and Health (NSDUH) collects information through face-to-face household interviews about the use of illicit drugs, alcohol, and tobacco among the U.S. noninstitutionalized civilian population aged ≥12 years. Respondents include residents of households and noninstitutional group quarters (e.g., shelters, rooming houses, dormitories, migratory workers' camps, and halfway houses) and civilians living on military bases. NSDUH variables include sex, age, race/ethnicity, residence (metropolitan/nonmetropolitan), annual household income, self-reported drug use, and drug use disorders. National Vital Statistics System Mortality (NVSS-M) data for U.S. residents include information from death certificates filed in the 50 states and the District of Columbia. Cases were selected with an underlying cause of death based on the ICD-10 codes for drug overdoses (X40-X44, X60-X64, X85, and Y10-Y14). NVSS-M variables include decedent characteristics (sex, age, and race/ethnicity) and information on intent (unintentional, suicide, homicide, or undetermined), location of death (medical facility, in a home, or other [including nursing homes, hospices, unknown, and other locations]) and county of residence (metropolitan/nonmetropolitan). Metropolitan/nonmetropolitan status is assigned independently in each data system. NSDUH uses a three-category system: Core Based Statistical Area (CBSA) of ≥1 million persons; CBSA of <1 million persons; and not a CBSA, which for simplicity were labeled large metropolitan, small metropolitan, and nonmetropolitan. Deaths from NVSS-M are categorized by the county of residence of the decedent using CDC's National Center for Health Statistics 2013 Urban-Rural Classification Scheme, collapsed into two categories (metropolitan and nonmetropolitan). RESULTS Although both metropolitan and nonmetropolitan areas experienced significant increases from 2003-2005 to 2012-2014 in self-reported past-month use of illicit drugs, the prevalence was highest for the large metropolitan areas compared with small metropolitan or nonmetropolitan areas throughout the study period. Notably, past-month use of illicit drugs declined over the study period for the youngest respondents (aged 12-17 years). The prevalence of past-year illicit drug use disorders among persons using illicit drugs in the past year varied by metropolitan/nonmetropolitan status and changed over time. Across both metropolitan and nonmetropolitan areas, the prevalence of past-year illicit drug use disorders declined during 2003-2014. In 2015, approximately six times as many drug overdose deaths occurred in metropolitan areas than occurred in nonmetropolitan areas (metropolitan: 45,059; nonmetropolitan: 7,345). Drug overdose death rates (per 100,000 population) for metropolitan areas were higher than in nonmetropolitan areas in 1999 (6.4 versus 4.0), however, the rates converged in 2004, and by 2015, the nonmetropolitan rate (17.0) was slightly higher than the metropolitan rate (16.2). INTERPRETATION Drug use and subsequent overdoses continue to be a critical and complicated public health challenge across metropolitan/nonmetropolitan areas. The decline in illicit drug use by youth and the lower prevalence of illicit drug use disorders in rural areas during 2012-2014 are encouraging signs. However, the increasing rate of drug overdose deaths in rural areas, which surpassed rates in urban areas, is cause for concern. PUBLIC HEALTH ACTIONS Understanding the differences between metropolitan and nonmetropolitan areas in drug use, drug use disorders, and drug overdose deaths can help public health professionals to identify, monitor, and prioritize responses. Consideration of where persons live and where they die from overdose could enhance specific overdose prevention interventions, such as training on naloxone administration or rescue breathing. Educating prescribers on CDC's guideline for prescribing opioids for chronic pain (Dowell D, Haegerich TM, Chou R. CDC guideline for prescribing opioids for chronic pain-United States, 2016. MMWR Recomm Rep 2016;66[No. RR-1]) and facilitating better access to medication-assisted treatment with methadone, buprenorphine, or naltrexone could benefit communities with high opioid use disorder rates.

Job/Housing Imbalance and Commuting Time in the Atlanta Metropolitan Area: Exploration of Causes of Longer Commuting Time

Abstract: Commuting is the major source of congestion and air pollution in the United States. For almost a decade, urban policy-makers have been concerned about the geographical balance between locations of jobs and housing as a strategy for reducing traffic congestion and air pollution in American cities. Despite the popularity and apparent acceptance of the job/housing (J/H) imbalance concept among public policy-makers, little empirical research has been done on the J/H imbalance and how it relates to commuting patterns. This research examines commuting patterns in the Atlanta metropolitan area to determine the extent to which commuting flow volume is the result of an imbalance between the location of home and workplace by using the most sophisticated and largest geographical scale data provided by the 1990 U.S. Census of Transportation Planning Package. This paper uses a Geographic Information System (GIS) to measure the job/housing imbalance within a commuting catchment area having a 7-mile radius from the cent...
