Households can be classified as family household or non-family household. When two or more people are living in a house and sharing food and shelter, it is a family household whereas a person living alone, or living with someone, to whom he/she is not related, is considered a non-family household. Households tend to go through a life cycle as this is the basic evolutionary process of a human’s life. This life cycle can be grouped in three different aged distributions, individuals of less than 35 years of age are classified as young, 35-64 are categorized as middle-aged and 64 above are old. The young age households can be further classified in the categories of single, young married, full nest, and single parent. The chosen stage for the scope of this paper is young single. According to ABS, the median age at marriage in Australia is 29.6 years for males and 27.7 for females, so the young single category includes males falling in the age range of 15 to 29.6 years and females in the age range of 15 to 27.7 years (as the households of age less than 15 are considered as children). As the name suggests young singles, so the marital status of this class of households is unmarried i.e. single, and as far as the characteristic of their children is concerned, a very small fraction of these households are single parents and this small number is dominated by females who like to raise children on their own without having any committed relationship or marriage.
户可以分为家庭和非家庭。当两个或更多的人生活在一个房子和分享食物和住所，这是一个家庭而独自一个人生活，或生活的人，他/她是不相关的，被认为是一个非家庭。家庭往往要经过一个生命周期，因为这是人的生命进化的基本过程。这个生命周期可以分为三个不同的年龄分布，年龄小于35岁的人被列为青年，35-64分为中64以上是老。年轻的年龄的家庭可以进一步分为单，年轻的已婚，满巢的类别，和单亲。选择阶段，本文的范围是年轻的单身。根据ABS的，在澳大利亚结婚的平均年龄的男性和27.7的女性29.6岁，如此年轻的单一类别包括男性落在15到27.7岁的年龄范围15至29.6岁和女性的年龄范围（如年龄小于15被认为是儿童的家庭）。顾名思义单身的年轻人，所以这类家庭的婚姻状况未婚即单，并尽自己孩子的特点有关，这些家庭中很小的一部分是单亲父母和这个小数量是女性喜欢占主导地位的提高孩子对自己没有任何承诺的关系或婚姻。
