As address-based sampling becomes increasingly popular for multimode surveys, researchers continue to refine data-collection best practices. While much work has been conducted to improve efficiency within a given mode, additional research is needed on how multimode designs can be optimized across modes. Previous research has not evaluated the consequences of mode sequencing on multimode mail and phone surveys, nor has significant research been conducted to evaluate mode sequencing on a variety of indicators beyond response rates.

Highly accurate landline samples may be drawn for national, state, county, or even smaller areas; however, wireless samples have less geographic precision. This requires additional data collection effort and screening costs in order to ensure the appropriate geographic area is surveyed.

Design: Cross-sectional, using data from the 2005 National Health Interview Survey and Cancer Control Supplement.
Setting: United States.
Background: Literature on the socio-economic 'gradient' in health often asserts that income is associated with better health not only for the very poor, but also across the entire income distribution. In addition, changes in the shape of the association between incomes during a period of increasing economic inequality have not been previously studied. The goal of the current study was to estimate and compare the shape of the relationship between income and mortality in the USA for the 1970s, the 1980s and the 1990s.
