This dashboard provides a detailed analysis of Portland's age demographic distribution, offering insights into how different age groups are spread across the city's neighborhoods.
Our data reveals significant variations in the median age across different census tracts within Portland:
The population distribution across different age groups is as follows:
Despite the 61+ years age group being the largest in terms of population size, the median age of the population is younger, specifically between 31 and 40 years. This discrepancy can be attributed to the distribution of the population across various age groups. While the 61+ age group has a significant number of individuals, the combined population of younger age groups (18-30 years, 31-40 years, and 41-50 years) is substantial enough to lower the overall median age. Additionally, the presence of younger families and working-age adults in Portland contributes to a lower median age, reflecting a balanced age distribution rather than a skewed one.

Bar Chart: The bar chart displays the number of census tracts within each median age range. It clearly shows that the 31-40 years age range is the most prevalent, with 120 tracts falling into this category.
Pie Chart: The pie chart breaks down the population by age group, emphasizing that the majority of Portland's population is within the 61+ years range. This chart offers a quick overview of the population distribution across different age groups.
