OLRC (Ordered Logit Regression Coefficient) cannot be interpreted as an absolute effectsize. The coefficients only denote relative differences in correlation and whether the correlations are negative or positive. E.g. in Peru and the USA there are negative correlations between happiness and having (more) children, in Sweden there are positive correlations. In most nations we see positive and negative correlations simultaneously, dependent on the actual number of children.
