The purpose of this study was to examine the relationship between safety and security index and human development. Descriptive statistics allowed to determining the mean of the independent variable safety and security index, and the dependent variable, human development. Using the mean of the independent variable as reference, I divided the participants into two groups including Low SS and High SS. Thereafter, I computed a one-way ANOVA to analyze the data. The ANOVA was significant, the effect size was strong, allowing to rejecting the null hypothesis, and indicating that there is a statistically significant relationship with strong effect size between safety and security index and human development. Furthermore, a post-hoc test indicated that High SS countries had significantly higher human development than Low SS countries, indicating that human development improves with an increase of safety and security. These results support the conclusion that there is a statistically significant and strong relationship between safety and security index and human development.
