The purpose of this analysis is to determine the significance of the factors: population, population density, and inflation rate on the measurement of the standard of living. The study considers demographic and economic data from 10 EU member states and employs a multiple linear regression model to analyze the impact of these variables on the standard of living, which is measured as the ratio between GDP per capita and final consumption expenditures per capita. The research aims to identify how much of the variation in the standard of living can be explained by the selected independent variables and to understand their individual significance.

Introduction

The standard of living serves as a vital indicator of a country's economic health and quality of life for its population. Economists have long sought to understand the factors influencing this measure, which encompasses income levels, access to resources, and overall economic prosperity. This study investigates the influence of population, population density, and inflation rate on the standard of living within the European Union (EU) context, leveraging a quantitative approach through multiple linear regression analysis.

Literature Review

The evaluation of factors affecting the standard of living has been a focus of numerous economic studies. Romer (1986) emphasized the role of increasing returns to scale and technological progress as drivers of economic growth, which indirectly influence living standards. Wolff’s (1991) analysis highlighted capital formation and productivity convergence as long-term contributors. Mankiw et al. (1992) contributed empirical evidence linking savings, productivity, and income levels to income per capita. Ravallion (1994) discussed measurement errors in assessing living standards, emphasizing the importance of accurate data. Recent studies by Cooper et al. (2015) have incorporated technological change considerations into welfare evaluations, recognizing dynamic influences. Despite varied approaches, the consensus underscores the importance of demographic and economic factors, such as population size, density, and inflation, in shaping living standards.

Methodology

This study employs panel data comprising ten EU countries over a defined period. The dependent variable, the standard of living (SOL), is calculated as the ratio of GDP per capita to total consumption expenditure per capita. The independent variables include population (POP), population density (DENSPOP), and inflation rate (INFL). The regression model is specified as:

SOLt = α + β1  POPt + β2  DENSPOPt + β3 * INFLt + εt

where ‘t’ represents the time period, and εt is the error term. Data was sourced from official statistical agencies and Eurostat databases, ensuring consistency and reliability.

Statistical Analysis

The data analysis was performed using EViews software, which facilitated estimating model parameters, hypothesis testing, and model validation. The model's significance was assessed through F-statistics, R-squared, and p-values for individual coefficients, with particular attention to the signs and magnitudes of β coefficients to interpret impact directions.

Results and Interpretation

The regression results revealed that the constant term (α) is approximately 3.55, indicating the baseline level of the standard of living when independent variables are zero. The coefficient for population (β1) was -0.33, statistically significant at p

The population density coefficient (β2) was positive, about 0.0053, and statistically significant, suggesting that higher density may facilitate economic activities, social interaction, and infrastructure development, thereby potentially enhancing living standards.

Regarding inflation (β3), the coefficient was positive (approximately 0.0211) and significant, indicating that higher inflation rates might be associated with increased living standards, possibly due to short-term monetary expansion effects or other macroeconomic dynamics. However, this relationship warrants cautious interpretation, as prolonged inflation could have adverse effects not captured within this model.

The R-squared value was approximately 0.203, meaning about 20.3% of the variation in the standard of living is explained by these three variables. The model passed significance tests, with the F-statistic indicating overall model validity and the Durbin-Watson test suggesting minimal autocorrelation issues.

Discussion

These findings highlight the complex interplay between demographic and economic factors influencing living standards. The negative association between population and SOL aligns with classical theories where overpopulation strains resources, thereby reducing per capita welfare. Conversely, the positive impact of population density might reflect benefits from agglomeration effects, such as increased economic productivity and better infrastructure.

The positive link between inflation and SOL may reflect transitional economic conditions or policy responses, though persistent high inflation often erodes real income and stability. The relatively low R-squared indicates that other variables—such as unemployment rates, social expenditure, education levels, or technological advancements—are also vital in determining living standards, suggesting avenues for further research.

Conclusion

This study confirms that population size, density, and inflation rate significantly influence the standard of living within EU countries, with the direction of effects aligning with existing economic theories. To enhance the explanatory power of the model, future research should incorporate additional socio-economic variables and extend the data set across longer time horizons. Policymakers should consider these factors when designing strategies aimed at improving residents' welfare, emphasizing sustainable population growth, infrastructure development, and macroeconomic stability.
