heading my common usage understanding of the word is that it means statistical information about something or the study thereof my own dictionary says demographics data resulting from the science of demography and demography the scientific study of human populations especially with relation to their size structure and distribution so on that basis the articles would be correctly titled 'demographics of ' and quote lots of statistics it would appear to me that according to my quite large dictionary the article is wrong in its definition of these two terms at the least it should explain that there is a possible different understanding of the terms my own interest was how broad the term demographics is and whether when discussing a population it would include information about the land area climate how wet it is all that sort of stuff which undoubtedly affects and influences the people living there even though it might not be the sort of information collected by modern advertising executives i suspect that a difference in understanding of the terms has crept in because such people are only interested in a subset of the total information i completely agree with you dictionary however the key phrase is the scientific study of human populations once human population is no longer an essential part of the study as in climate landmass etc which will be the same regardless of population it is no demography i do agree that if climate has an effect on the population e g in the arctic region people tend to protect themselves against cold it is interesting from demography but without such reference not non families i notice that a lot of wikipedia articles use some sort of template putting households into four categories had children under the age of living with them were married couples living together had a female householder with no husband present and non families these categories do not add up to for examples see downers grove willowick ohio etc etc any ideas about where this came from and how it can be addressed it seems like a category generated as part of a marketing strategy novickas generational cohorts are those born during the brief period generation less that's exactly what i was thinking what's the deal i'll quote below generation x cohort born from to memorable events challenger explosion iran contra social malaise reaganomics aids safe sex fall of berlin wall single parent families key characteristics quest for emotional security independent informality entrepreneurial generation y cohort also called n generation born from to seems to be years through are wandering generation lost i was recently at a business conference and they where talking about the generations and they referred to the n generation as the milenials or the milenial generation those who haven't known a time before the computer
