In Brownell et al. (2001), breastfeeding duration (how long a baby was breastfed) rates are based on National Longitudinal Survey of Children and Youth (NLSCY) 1996 survey data for Manitoba , where the length of breastfeeding was reported by the mother for any child less than 2 years of age at the time of survey. The mother was asked if the infant was initially breastfed, and if so, for how long. One of the possible answers was "still breastfeeding".

In Brownell et al. (2008), breastfeeding duration rates were calculated using information from three cycles of the Canadian Community Health Survey (CCHS) (1.1, 2.1and 3.1). In the survey, women were asked about whether they had given birth in the past five years, and for those who did, whether they breastfed their baby, whether they were still breastfeeding their baby, and if not, how long they breastfed their baby.
