The article "Part-time by choice" (November 2000) showed an incorrect formula for shift-share analysis in note 3. The correct version is:
Beginning with January 2001 data, estimates from the Survey of Employment, Payrolls and Hours (SEPH) are based on the North American Industry Classification System (NAICS). The NAICS-based estimates are not comparable to the previously published estimates based on the Standard Industrial Classification (SIC) of 1980. In order to facilitate the transition, NAICS-based historical series have been produced from January 1991 to December 2000. The estimates of employment and average earnings reflect NAICS-based levels derived from the administrative sample and modifications to the industrial coverage and methodology of the survey. In addition, seasonal factors have been revised to improve the historical consistency of seasonally adjusted estimates. These changes are reflected in this month's online charts in "Key labour and income facts."
A concordance table between NAICS and 1980 SIC codes is available on request. A description of the conversion process and its impact on the data are available in the April 2001 issue of Employment, earnings and hours (Catalogue no. 72-002-XIB; 72-002-XPB). For more information on NAICS, consult the "NAICS Canada table of contents" page on Statistics Canada's Web site (www.statcan.ca), or contact the Labour Statistics Division at email@example.com.
Beginning this month, as an enhancement to our online "Key labour and income facts" section, we will be adding a series of "Fact sheets." These brief updates, available free in downloadable (PDF) format, will highlight recent statistics and trends on several popular themes, including gambling, work absences, unionization, and age of retirement. This month we feature a Fact sheet on gambling, which shows that net revenue from government-run lotteries, video lottery terminals and casinos rose from $2.7 billion in 1992 to $9.0 billion in 2000. Fact sheets for other topics will be introduced as new data become available.
As always, we welcome your comments and suggestions.
