Social Transfers, Earnings and Low-Income Intensity Among Canadian Children, 1981-96: Highlighting Recent Development in Low-Income Measurement

Abstract

In this paper, we revisit trends in low-income among Canadian children by taking advantage of recent developments in the measurement of low-income intensity. We focus in particular on the Sen-Shorrocks-Thon (SST) index and its elaboration by Osberg and Xu. Low-income intensity declined in the 1980s but rose in the 1990s. Declining earnings put upward pressure on low-income levels over much of the period. Higher transfers more than offset this pressure in the 1980s and continued to absorb a substantial share of the increase through 1993. In contrast, the rise in low-income intensity after 1993 reflected reductions in UI and social assistance benefits that were not offset by increased employment earnings, at least to 1996 the latest year used in this paper.

A major aim of the paper is methodological. We contrast results using the SST index with results produced by the more familiar low-income rate, the usual measure for indexing low-income trends. The low-income rate is embedded in the SST index, but unlike the index, the rate incorporates only partial information on the distribution of low-income. Consequently, the low-income rate is generally unable to detect the changes we describe and this is true irrespective of the choice of low-income cut-off. Compared to the low-income intensity measure, the rate is also relatively insensitive to changes in transfer payments and employment earnings.
