such as Jordan, Jamie, Jesse, Morgan, Leslie/Lesley, Joe/Jo, Jackie, Pat, Dana, Alex, Chris/Kris, Randy/Randi, Lee, etc. Often, use for one gender is predominant. Also, a particular spelling is often more common for either men or women, even if the pronunciation is the same. Many culture groups, past and present, did not or do not gender names strongly, so that many or all of their names are unisex. On the other hand, in many languages including most Indo-European languages (but not English), gender is inherent in the grammar. Some countries have laws preventing unisex names, requiring parents to give their children sex-specific names. Names may have different gender connotations from country to country or language to language. Within anthroponymic classification, names of human males are called andronyms (from Ancient Greek ἀνήρ / man, and ὄνυμα [ὄνομα] / name), while names of human females are called gynonyms (from Ancient Greek γυνή / woman, and ὄνυμα [ὄνομα] / name). Popularity The popularity (frequency) distribution of given names typically follows a power law distribution. Since about 1800 in England and Wales and in the U.S., the popularity distribution of given names has been shifting so that the most popular names are losing popularity. For example, in England and Wales, the most popular female and male names given to babies born in 1800 were Mary and John, with 24% of female babies and 22% of male babies receiving those names, respectively. In contrast, the corresponding statistics for England and Wales in 1994 were Emily and James, with 3% and 4% of names, respectively. Not only have Mary and John gone out of favour in the English speaking world, the overall distribution of names has also changed significantly over the last 100 years for females, but not for males. This has led to an increasing amount of diversity for female names. Choice of names Education, ethnicity, religion, class and political ideology affect parents' choice of names. Politically conservative parents choose common and traditional names, while politically liberal parents choose the names of literary characters or other relatively obscure cultural figures. Devout members of religions often choose names from their religious scriptures. For example, Hindu parents may name a daughter Saanvi after the goddess, Jewish parents may name a boy Isaac after one of the earliest ancestral figures, and Muslim parents may name a boy Mohammed after the prophet Mohammed.
