The authors examine the longitudinal fortunes of the poorest fifth of U.S. metropolitan neighborhoods, defined as those with 20% or higher poverty rates in 1980. They employ logistic regression to identify the factors correlated with 1980-1990 increases and decreases in poverty rates across these poor neighborhoods and examine whether factors vary by predominant racial/ethnic composition. Regional economic cycles and population growth performance are the dominant determinants of neighborhood poverty change, although the neighborhood's initial poverty rate also influences it. Neighborhoods with higher poverty rates in 1980 evince less stability. Extremely poor neighborhoods are roughly as likely to experience an increase in poverty of 5 or more percentage points as a comparable decrease in poverty. The authors conclude that continued poverty is not the only or even most likely fate of poor neighborhoods; their fortunes depend on both local and regional context.

This research builds on three decades of effort to produce national estimates of the amount and rate of force used by law enforcement officers in the United States. Prior efforts to produce national estimates have suffered from poor and inconsistent measurements of force, small and unrepresentative samples, low survey and/or item response rates, and disparate reporting of rates of force. The present study employs data from a nationally representative survey of state and local law enforcement agencies that has a high survey response rate as well as a relatively high rate of reporting uses of force. Using data on arrests for violent offenses and the number of sworn officers to impute missing data on uses of force, we estimate a total of 337,590 use of physical force incidents among State and local law enforcement agencies during 2012 with a 95 percent confidence interval of +/- 10,470 incidents or +/- 3.1 percent. This article reports the extent to which the number and rate of force incidents vary by the type and size of law enforcement agencies. Our findings demonstrate the willingness of a large proportion of law enforcement agencies to voluntarily report the amount of force used by their officers and the relative strengths and weaknesses of the Law Enforcement Management and Administrative Statistics (LEMAS) program to produce nationally representative information about police behavior.

This study describes changes in the use of sworn volunteers among the nation's local law enforcement agencies and identifies those state-level certification, community, and agency characteristics associated with agencies using such volunteers in 2013. Law Enforcement Management and Administrative Statistics data from 1999 through 2013 were analyzed to document trends in both the number of sworn volunteers and the prevalence of agencies using sworn volunteers. While there has been a modest decline in the use of sworn volunteers since 1999, in 2013, about 36% of all local law enforcement agencies used sworn volunteers; furthermore, these volunteers comprised 7% of all local sworn personnel having arrest authority nationwide in 2013. A survey of peace officer standards and training agencies found that approximately two thirds of states required state-level certification of sworn volunteers. Multivariate analyses of state-level certification standards, census data, and agency characteristics found that agencies were more likely to use sworn volunteers if they (a) are a sheriff's office, (b) serve jurisdictions with larger populations, (c) have greater levels of social disadvantage, (d) do not require recruits to have more than a high school education, or (e) are located within states offering graduated levels of sworn volunteer certifications. Agencies were less likely to use volunteer officers if they (a) hire part-time sworn officers, (b) have a greater entry-level salary, or (c) are accredited.
