What are measurable physical changes that occur throughout a person's life known as?

The term that accurately describes measurable physical changes occurring throughout a person's life is "growth." This concept specifically refers to quantifiable changes in size, height, weight, and other physical attributes that are often tracked throughout childhood and into adulthood. Growth is usually assessed using standard measurements and can be observed at various stages of life, such as infancy, childhood, adolescence, and even into early adulthood.

In contrast, development refers to the broader range of changes that include cognitive, emotional, and social aspects, not just physical ones. Maturation involves the process of becoming fully developed or mature, which can include both physical and non-physical changes. Transformation generally conveys a significant change in form, appearance, or character and is less specific than growth in the context of physical changes. Thus, "growth" specifically captures the essence of measurable physical changes throughout a person’s life.
