Not much. The polar areas would be uninhabitably cold no matter what the axial tilt of the Earth is. The equatorial regions would be hot, and the mid-latitudes are more temperate. The population distribution around the Earth is primarily impacted by arable land area, and less so by migration paths around the world.
So India and China are most densely populated, with Australia (cut off by oceans) and North America (only relatively recently re-populated after the Clovis impact extinctions) with the lowest density.
The Earth's tilt is what causes the seasons.
Earth's axial tilt is 23.44°.

The tilt of the Earth's axis, approximately 23.5 degrees, is primarily due to the planet's formation and subsequent collisions with other celestial bodies during its early history. This axial tilt influences the distribution of sunlight received by different regions, leading to the seasonal changes we experience. The tilt remains relatively stable over long periods, although it can undergo slight variations due to gravitational interactions with other celestial bodies.
The tilt of Earth's rotation axis creates the different seasons by causing the amount of sunlight received at a given location to vary throughout the year. This tilt also affects climate patterns and the distribution of temperatures on Earth's surface, impacting weather systems and ecosystems.
Earth's tilt is much older than that - it probably had its tilt for millions of years.
