'Replacement level fertility' is a technical term which seems almost self-explanatory. However there are some important qualifications which make it a more difficult concept than might be supposed. Also, the relationship between replacement level fertility and zero population growth is complicated. The article explains why this is so and thus why, although the United Kingdom's current level of fertility is below replacement level, population is projected to grow for the next thirty years.
