In Mexico, there has been an upward trend in mortality rates from colorectal cancer (CRC) over the past three decades. This tumor is ranked among the ten most prevalent causes of morbidity from malignancies in Mexico. To determine the mortality trends by socioeconomic region and by state, and to establish the relative risk between both educational level and socioeconomic region with mortality from CRC within the time frame of 2000-2012. Records of mortality associated with colorectal cancer were obtained. Rates of mortality by state and by socioeconomic region were calculated, along with the strength of association (obtained through the Poisson regression) between both socioeconomic region and educational level and the mortality from CRC. A total of 45,487 individuals died from CRC in Mexico from 2000 to 2012. Age-adjusted mortality rates per 100,000 inhabitants increased from 3.9 to 4.8. Baja California, Baja California Sur, and Sonora had the highest mortality from CRC. Individuals with no school or incomplete elementary school had a higher risk of dying from this cancer (RR of 3.57, 95% CI: 3.46-3.68). Region 7 had the strongest association with mortality from CRC (Mexico City: RR was 2.84, 95% CI: 2.39-3.37 [2000] and 3.32, 95% CI: 2.89-3.82 [2012]). In Mexico, the age-adjusted mortality rates per 100,000 inhabitants that died from CRC increased from 3.9 to 4.8 in the study period, using the world population age distribution as the standard. Baja California, Baja California Sur, and Sonora had the highest mortality from CRC. Mexico City, which was socioeconomic region 7, had the strongest association with mortality from CRC. En México ha habido una tendencia al alza en las tasas de mortalidad por cáncer colorrectal (CCR) en las últimas 3 décadas. Esta neoplasia está clasificada dentro de las 10 causas más frecuentes de morbilidad por neoplasias malignas en México. Determinar las tendencias de la mortalidad por CCR por región socioeconómica y por estado, así como establecer el riesgo relativo entre el nivel de educación y la región socioeconómica con la mortalidad por CCR en el periodo 2000-2012. Se obtuvieron los registros de mortalidad por CCR. Se calcularon las tasas de mortalidad por estado y por región socioeconómica, así como la fuerza de asociación (mediante la regresión de Poisson) entre la región socioeconómica y el nivel de educación con la mortalidad por CCR. En México, en los años 2000-2012, 45,487 personas murieron por CCR. Las tasas de mor
