Why do first-born children tend to be more successful than younger siblings?

First-born children may achieve greater success due to factors like early germ exposure, which affects younger siblings more severely, and receiving more parental attention throughout their childhood.

How do germs affect the success gap between siblings?

Younger siblings are more likely to suffer severe respiratory illnesses in their first year, which can hinder brain development and negatively impact adult wages. This health shock is estimated to explain half of the wage gap.

What role does parental attention play in sibling success?

First-born children receive more daily quality time throughout their childhood, which can provide crucial brain-boosting stimulation during their early development compared to younger siblings.

Germs Give Eldest Siblings an Edge?

Summary

First-borns achieve higher success in education and income.
Younger siblings are more prone to severe respiratory illnesses.
Extra parental attention boosts first-borns' development.

New research suggests that germs, not personality, explain why first-born children often achieve greater success in education and income. Younger siblings are notably more susceptible to severe respiratory illnesses during their first year, with Danish data indicating a two to three times higher likelihood of hospitalization compared to their older siblings. These early health challenges can impede brain development, leading to a lasting impact on adult wages.

The study estimates that illness accounts for about half of the wage gap between first- and second-borns. The remaining difference is attributed to parental behavior. First-born children receive an estimated 20-30 minutes more quality time per day throughout childhood, potentially providing crucial brain-boosting stimulation in their formative years.
