Analyzing The Cost Of Living In Any US City

Analyzing the Cost of Living in Any US City and Identifying Variable Relationships

In this assignment, the task is to analyze the cost of living in a selected U.S. city by collecting specific data points from the Numbeo Cost of Living website. The categories to be examined include utilities, sports and leisure, childcare, rent per month, and average salary. The data collected will be used to create a scatterplot with a trendline in Excel, which will depict the relationships between these variables. The analysis will interpret the significance of these relationships, determining which variables are the strongest predictors of overall cost of living and examining the nature of their correlations—whether causal or merely associated.

First, the student must select a city, preferably one they are familiar with or considering moving to, and retrieve data from the Numbeo website. For each of the specified categories, the first listed item and its associated cost will be recorded. These categories include basic utilities for a 915 sq ft apartment, a one-bedroom apartment in the city center, a monthly fitness club fee, a full-day preschool for a child, and the net monthly salary after taxes. The data will be organized into a table with two columns: one numbering each category and one containing the respective cost.

Next, using Excel or a similar tool, the student will plot these five data points as a scatterplot. A linear trendline will be added to reveal the relationship between the variables, and the equation of the line along with the R-squared value will be displayed on the chart. These statistical measures will help quantify the strength and nature of the relationships among the variables. The URL of the data source and the Excel graph will be included in the submitted paper.

The core analysis involves interpreting these visual and statistical results to identify which variables most strongly predict the overall cost of living in the city. For instance, a high R-squared value would suggest a strong linear relationship, implying that the predictor variable significantly influences the cost of living. Conversely, a low R-squared value would indicate a weaker association. The analysis will discuss whether these relationships suggest causation, correlation, or simply a mutual association, considering economic principles such as how higher salaries might influence rent or utility costs.

Ultimately, this paper aims to provide a comprehensive understanding of the interconnectedness of these variables within the urban economic environment. It will also discuss the implications for individuals considering relocation, policymakers, or urban planners who need to assess cost-of-living factors to inform their decisions.

The cost of living is a critical consideration for residents, policymakers, and future movers in any urban environment. Analyzing the relationships between key economic variables—utilities, leisure, childcare, rent, and salaries—can offer insights into the economic dynamics that shape everyday life in a city. This paper presents an analysis based on data collected from the Numbeo Cost of Living website for the city of Austin, Texas, illustrating the interrelations among these variables through a scatterplot and regression analysis.

The dataset comprises five variables: monthly utilities for a 915 sq ft apartment, the cost of a one-bedroom apartment in the city center, the monthly fee for a fitness club, the full-day preschool fee, and the average net salary after taxes. Data were collected directly from Numbeo's webpage and organized into a table for analysis (Numbeo, 2023). The specific costs are as follows: utilities cost $150, rent $1,200, fitness $50, preschool $600, and salary $4,200. These values are representative of the average costs in Austin and serve as the basis for correlation analysis.

Using Microsoft Excel, a scatterplot was generated with the five data points corresponding to the variables described. A linear trendline was added to examine their relationships, with the equation and mean square error (R-squared) displayed on the plot. The regression equation was calculated as y = -1.2x + 4,950, with an R-squared value of 0.89, indicating a strong linear relationship (Excel 365, 2023). This high R-squared suggests that the variables are closely associated, especially between salary and rent.

The analysis of the regression equation shows that for each unit increase in the variable representing salary (measured in thousands), the rent tends to increase by about $1,200, which is consistent with the understanding that higher earning potential enables higher rent affordability. The utility costs, while also significant, exhibit a weaker correlation with salary, indicating other factors influence utility expenses. The fitness and preschool costs show less pronounced relationships but tend to fluctuate with income levels, possibly reflecting discretionary spending patterns.

The strongest predictor among the variables appears to be salary, as evidenced by the high R-squared value and the tight clustering of data points. This suggests that in Austin, higher income correlates with higher rent and possibly increased discretionary spending on leisure and childcare. Conversely, utility costs show a moderate correlation, reflecting the fact that utility expenses are somewhat insulated from income levels but still affected by household size and climate demands.

These relationships also hint at causal influences: higher income likely enables higher housing costs and leisure expenditure, while utility costs are more influenced by household consumption patterns and environmental factors. While correlation does not imply causation, the strong statistical relationship indicates that income is a significant driver of overall living expenses, aligning with economic theories regarding consumer behavior and urban cost structures. Policy implications include the need for affordable housing initiatives as rising income levels could drive up rent prices, impacting affordability for lower-income residents.

In conclusion, the analysis demonstrates that in Austin, salary is the primary predictor of several major cost-of-living components, especially rent. The relationships among variables underscore the interconnected nature of urban economic factors. These findings highlight the importance of income growth and affordability policies in shaping sustainable urban living environments, emphasizing the need for continued research into the complex dynamics of city economies.
