Correlation matrix among demographic variables and sleep health

Variable	1	2	3	4	5	6
1. Sleep health
2. Man vs woman or nonbinary/trans	0.021
3. Age	0.188*	0.032**
4. Country income classification	0.123**	0.033**	0.079**

7. Dependent <18 years in home vs not	−0.005	−0.031**	−0.067**	−0.093**	0.300*	0.069**

Because correlations and linear regressions require variables to be continuous or dichotomous, women and the small group of nonbinary/trans individuals were combined in order to compare the connections between the primary study variables and these 2 gender groups relative to men.
