Trends in spending on eating away from home in Brazil, 2002-2003 to 2008-2009

The study aims to describe trends in food consumption away from home in Brazil from 2002-2003 to 2008-2009 and to analyze the influence of income on this behavior. The authors used data collected by the Household Budget Surveys conducted by the Brazilian Institute of Geography and Statistics (IBGE) in 2002-2003 and 2008-2009. The information analyzed in this study involves records of food and beverage purchases for consumption away from home. Trends in eating away from home were estimated for the total population and according to demographic and economic strata. The association between the share of food consumed away from home and income was studied using regression models to estimate income elasticity coefficients. The share of eating away from home increased 25% during the period, reaching 28% of total spending on food. Each 10% increase in mean per capita income leads to a 3.5% increase in the share of food consumed away from home. This suggests that income growth will result in future increases in the share of eating away from home.

本研究旨在描述2002-2003年至2008-2009年巴西户外食品消费的趋势变化，并分析收入对该消费行为的影响。研究人员采用了巴西地理与统计研究所（IBGE）于2002-2003年及2008-2009年开展的家庭预算调查所采集的数据。本研究分析的信息涵盖了户外消费的食品与饮料采购记录。研究人员针对全体人口及不同人口学、经济分层群体，估算了户外食品消费的趋势变化。通过回归模型估算收入弹性系数，本研究探究了户外食品消费占比与收入水平之间的关联。研究周期内，户外食品消费占比提升了25%，最终达到食品总支出的28%。人均收入每增长10%，户外食品消费占比将提升3.5%。这一结果表明，未来收入增长将持续推动户外食品消费占比的提升。
