Actually, children today are generally taller than in past generations, not shorter—on average. This trend is known as the secular trend in growth, where improvements in nutrition, healthcare, hygiene, and living standards over the last century have led to increases in average height across many populations.

However, there are exceptions and recent concerns that might be contributing to the idea that children are getting shorter:

1. Stalling or Reversals in Some Countries: In some developed countries (like the US or UK), the gains in height have plateaued or even slightly declined recently, possibly due to:

   • Increases in childhood obesity (which can affect growth patterns).

   • Poorer diet quality (ultra-processed foods, low nutrient density).

   • Socioeconomic inequality.

   • Rising stress levels or adverse childhood environments.

2. COVID-19 Pandemic Effects: During lockdowns, many children had reduced physical activity, less exposure to sunlight (vitamin D), and altered diets, potentially affecting growth spurts.

3. Regional Variation: Children in some low-income or war-affected countries may be experiencing stunted growth due to malnutrition or chronic illness, which could influence perceptions.

If you’re hearing or observing that “kids today are shorter,” it might reflect specific local conditions or social groups rather than a universal trend.
