The latter four codes were adopted on 1 January 1994. Marital statusĪfter the Act relating to registered partnership came into force on 1 August 1993, the following marital status types apply: Unmarried (not previously married), married, widow/widower, divorced, separated, registered partner, separated partner, divorced partner and surviving partner. A comparison of the two time series indicates that the number of children has been somewhat under-reported in the notifications of divorce/separations. Instead, the statistics published as of 2006 the number of children is calculated using information on parents/children relations back to 2001. In 2006, the Central Population Register stopped transferring the number of children from these notifications. Information on the number of children was taken from the notification of divorce/separation up until and including 2005. The regulations to the act were last amended effective 1 October 1998. Who is regarded as a resident of Norway and where in Norway a person shall be counted as a resident, is stipulated in the Population Registration Act of 16 January 1970. The marriage cohort of 1985 is the marriages contracted in 1985. The birth cohort of 1970 is those who were born in 1970. CohortĪ group of persons that has experienced the same (demographic) events the same calendar year (or period), such as birth or marriage. Mean populationĪverage population at the beginning and end of the year. Example: The age-specific divorce rate for women in a period is the annual number of divorced women in an age group in the period per 1 000 of the mean population of married and separated women in the same age group. Annual averages are published for five-year periods. Marriages between persons of opposite sexĮvents in a period divided by relevant mean population. At its worst, breaking the custom of arranged marriage can mean being disowned by one’s family.Marriages contracted. Youth who attend American schools and are immersed in Western culture still can experience extreme pressure from older relatives to marry someone from back home of the same religion and caste. These traditions and values span social class: The high level of educational and professional achievement in Indian immigrant populations can disguise how deeply traditional they are in their personal lives. More than 87 percent of Indian Americans are foreign-born, and ties to relatives and communities back home mean customs like arranged marriage and the shame of divorce continue to be enforced across oceans and through generations. Though it’s not clear exactly how many such unions exist in the United States, we know that South Asians are part of the fastest-growing racial group here, and about 70 percent of Indian marriages are arranged. The divorce stigma often is most severe in cases of arranged marriage. In some communities, what’s needed is more divorce, not less. So while many are cheering about the falling divorce rates in the United States, this isn’t good news for all. If their families oppose the divorce, they may be left with no place to go and no means of supporting themselves and their children. The divorce taboo has particularly severe consequences for women who have no financial resources of their own. In conservative families, a divorced woman is often viewed as pariah or harbinger of bad luck. Sometimes, they stop receiving invitations to family functions, and when they do attend, they’re made a target of relatives’ shaming. Divorcees often are isolated from their families, an object of mingled pity and disdain. While parents and siblings might show sympathy over an unhappy marriage, divorce is often considered beyond the pale. Husbands and wives are forced by social pressure originating 8,000 miles away to stay in emotionally unhealthy and abusive relationships. Chitra’s story, and the emotional suffering of other South Asian men and women whom I help as a counselor, show why those numbers are so concerning. ![]() ![]() ![]() If you use these in your planner or binder, you’ll likely slowly start filling your planner up.

Historically, the definition of a pyramid has been described by many mathematicians in ancient times. ![]() The edges connected from the polygonal base's vertices to the apex are called lateral edges. Each base edge and apex form an isosceles triangle, called a lateral face. All pyramids are self-dual.Ī pyramid is a polyhedron that may be formed by connecting a polygonal base and a point, called the apex. It can be generalized into higher dimension, known as hyperpyramid. Many types of pyramids can be found by determining the shape of bases, or cutting off the apex.
