This chart shows the Mother’s Index Rankings by Country.
Mothers are women who inhabit or perform the role of bearing some relation to their children, who may or may not be their biological offspring. Thus, dependent on the context, women can be considered mothers by virtue of having given birth, by raising their child(ren), supplying their ovum for fertilization, or some combination thereof. Such conditions provide a way of delineating the concept of motherhood, or the state of being a mother.
Women who meet the third and first categories usually fall under the terms ‘birth mother’ or ‘biological mother’, regardless of whether the individual in question goes on to parent their child. Accordingly, a woman who meets only the second condition may be considered an adoptive mother, and those who meet only the third a surrogacy mother.
Traditionally, and still in most parts of the world today, a mother was expected to be a married woman, with birth outside of marriage carrying a strong social stigma. Historically, this stigma not only applied to the mother, but also to her child. This continues to be the case in many parts of the developing world today, but in many Western countries the situation has changed radically, with single motherhood being much more socially acceptable now.
