Studies on the meat market behavior may result in interesting parameters for the market and public policy agents. The definition of the income-elasticity of poultry consumption enables the elaboration of prospective analysis on the potential demand of this product. Thus, the main objective of the present study is to estimate the income-elasticities of poultry consumption. Data from the 1995-96 and 1987-88 Consumer Expenditure Survey, published by IBGE (Brazilian Institute of Geography and Statistics), were used in the analysis. The elasticities were obtained by fitting a three-segment polygonal curve relating the logarithm of the per capita poultry meat consumption as a function of the per capita family income. Generalized Least Squares method was used for the econometric model fitting. The elasticities were obtained considering the total, carcasses and selected individual poultry parts consumption. Average income elasticity of the total consumption enables the classification of poultry meat as a normal product. The observed average income elasticities showed that breast and thighs are superior products. In the last period, a negative elasticity was observed for carcasses. Estudos sobre o comportamento de mercado de carnes podem gerar parâmetros de interesse para agentes do setor e formuladores de políticas. A definição da elasticidade renda do consumo de frango permite a elaboração de análises prospectivas sobre a demanda potencial desse produto. Dessa forma, o presente estudo teve por objetivo principal estimar as elasticidades-renda do consumo físico de carne de frango. Resultados da Pesquisa de Orçamento Familiares (POF) de 1987-88 e de 1995-96, publicados pelo IBGE (Instituto Brasileiro de Geografia e Estatística) foram utilizados na análise. As elasticidades foram obtidas por meio do ajustamento de uma poligonal com três segmentos relacionando o logaritmo do consumo físico per capta de carne de frango com o recebimento familiar per capta. Para o ajustamento do modelo foi utilizado o método de Mínimos Quadrados Generalizados. As elasticidades foram obtidas considerando o consumo total, o de carcaça e o de alguns corte individuais de frango. O resultado referente à elasticidade-renda média para consumo total permite classificar o frango como um bem normal. As elasticidades-renda médias obtidas apontam que o peito de frango e a coxa são bens superiores. No que se refere à carcaça (frango abatido na designação do IBGE), foi observado, para o último período, elasticidade-renda média negativa
