HCUPnet is a free, on-line system based on data from the Healthcare Cost and Utilization Project (HCUP). It provides access to health statistics and information on hospital inpatient and emergency department utilization. It allows users to generate tables and graphs on national and regional statistics and trends for community hospitals in the U.S. In addition, community hospital data are available for those States that have agreed to participate in HCUPnet.

Explaining the Consumer Price Index

Source: Adam Weber and John Peterson, Economic and Budget Issue Brief, Congressional Budget Office, June 20, 2007

The consumer price index for all urban consumers (CPI-U) is the best-known official measure of inflation. Published monthly by the federal Bureau of Labor Statistics (BLS), the CPI-U tries to approximate changes in the cost of living–that is, changes in the cost of maintaining a constant standard of living from one month to the next. To construct the CPI-U, BLS surveys the prices of thousands of goods and services (the index has more than 200 categories of items) in 38 regions, averaging the results to form a nationwide estimate of inflation. Over the past five years, the cost of living, as measured by the CPI-U, has varied but, on average, has risen by about 2-3/4 percent per year.

The purpose of this brief is to explain some of the methods used to construct the CPI-U and why, in some cases, the index’s estimates of inflation may differ from consumers’ perceptions of how much prices are rising.2 The brief focuses on six aspects of the CPI-U’s construction: averaging regional price indexes to create a nationwide index; estimating the expenditure weights that BLS assigns to the major categories of prices in the CPI-U to account for the categories’ relative importance; allowing for shifts in relative prices, a phenomenon known as economic substitution; adjusting for changes in the quality of various goods and services; measuring prices for medical care; and measuring prices for shelter.

Web Sites Start Reporting Hospital Mortality Data

The next evolution in quality reporting is here as outcomes data goes public.

As the number of public Web sites on hospital performance have flourished during the past couple of years, mortality data has been noticeably absent. That’s all changing. The question is: Are hospitals ready?

This month, the federal government’s Hospital Compare Web site, which posts data on how well hospitals meet performance measures, will for the first time publish 30-day mortality rates for heart attack and heart failure. Pneumonia will be added soon. Using Medicare claims data, the site will show whether a hospital’s death rate is better or worse than what is expected for a hospital’s patient population.

Labor Organizing Among Mexican-born Workers in the United States: Recent Trends and Future Prospects

This article surveys unionization patterns and other workplace-oriented organizing among Mexican-born workers since the mid-1990s. Although the number of Mexican-born union members grew during that decade, the unionized proportion declined, especially among noncitizens. The decline reflects the large proportion of new immigrants in the Mexican-born population and the increased geographic dispersion of immigration in recent years away from highly unionized states such as Illinois and California. Another factor is that recent Mexican immigrants are underrepresented in the most unionized sectors (such as government employment). However, unions, especially in California, have effectively mobilized Mexican immigrants into electoral politics in the 1990s, and new community-based organizations with a focus on economic justice have also recruited low-wage Mexican immigrant workers in occupations such as day labor and domestic service, in which conventional unionism is rare.

The Effects of Rounding on the Consumer Price Index

Source: Elliot Williams, Monthly Labor Review, Vol. 129 no. 10, October 2006

The Bureau of Labor Statistics rounds the Consumer Price Index (CPI) to a single decimal place before it is publicly released. Because the actual changes in the CPI have been small recently (the rate of inflation has been relatively low), the small differences in rounding the CPI index before calculating an inflation rate can create a significantly misleading picture of monthly price inflation. This article demonstrates how such problems can arise and investigates how frequently there is a discrepancy between inflation rates calculated from unrounded indexes and those calculated from rounded indexes under different possible rounding policies.
