The teen pregnancy rate in the United States developed nations. Teen pregnancy has substantial health, economic, and social costs. Pregnant teenagers are more likely to experience miscarriages, maternal illness (preeclampsia, hypertension, etc.), stillbirth, and neonatal death.
Oregon teen pregnancy data includes births and induced abortions to teens. Pregnancy estimates are based upon the estimated number of teen births and induced terminations among Oregon teens; they do not include the number of fetal deaths or miscarriages (spontaneous abortions) which occur.
Teen Pregnancy 4-3 OREGON FEMALES 18-19 In 2004, the pregnancy rate for Oregonians age 18 to 19 was parisons with the 2003 fi gures show a decrease in the birth rate
Teen Pregnancy Worldwide. 16 million girls ages 15-19 give birth each year; Global birthrate among 15-19 year old girls is 49 in 1,000; Complications of pregnancy is the 2nd highest cause of death in 15-19 year old girls
Teen Births is a rate. Teen Births is the number of births to females ages 15-19 per 1,000 females in a county. Rates measure the number of events (e.g., deaths, births, etc.) in a given time period (generally one or more years) divided by the average number of people at risk during that period.

B = Total live births during a given year.
The number of births per thousand in a given year is called crude birth rate , which is related to the total population. In the words of Thomson and Lewis, “The crude birth rate for any specified population is obtained by dividing the number of births recorded in that population during a specified year by its total numbers, which gives a fraction of birth per person.”
To calculate SFR, the number of females in one million population in a specific year is multiplied by their age specific birth rates which are then added to calculate the total number of births in all age groups 15-49 years.
Further, this measure of crude birth rate is not satisfactory because fertility is related to women and not to the whole population. Thus it is only a crude measure of fertility of a country. Method # 2. Corrected Birth Rate:
Crude or natural birth rates are different in any country at different times, because crude birth rate is calculated after a particular month of the year. Moreover, the data for live births is based on the registered births, but all births are not registered generally.
General Fertility Rate: The number of children born per year per thousand females in the age group of 15-49 years, is called the General Fertility Rate. In the words of Thomson and Lewis, “General Fertility Rate denotes the number of births per thousand women of child bearing age.”. It is calculated as follows:
This measure of fertility is also defective because it assumes that both birth and death rates remain constant during a generation. This is unrealistic. In fact, both birth and death rates are liable to change. Therefore, Thomson and Lewis opine that “these rates should not be used in making a prognosis of probable future growth of population.”
The pregnancy rate per 1,000 females 10-17 is calculated by dividing the 12-month moving total pregnancies by the most recent population estimate for Oregon females 10-17 years old, multiplied by 1,000. During the year, the data are under constant revision.
The Center for Health Statistics has recently developed a system to calculate preliminary teen pregnancy rates for the Oregon Benchmark age category of 10-17 year olds at the state and county level.
The 12-month moving total is the sum of monthly counts of teen pregnancies for 10-17 year old Oregon resident females (births + abortions* during the previous 12-month period.)**
Some years, it seems like everyone you know is having a baby. Other years, it might seem like giving birth is the last thing going on in your circle of friends. But, whether it affects you directly or not, birth surrounds you all the time; someone's probably being born at this very minute! And minute by minute, the number of people being born into the world starts to stack up.
When talking about CBR we look at the number of live births per year and use mid-year estimates. CBR is almost always reported per 1000 living people. The calculation for determining crude birth rate is (number of births) x 1000 / estimated population at mid-year. Population scientists use data from CBR as an easier number than fertility or pregnancy rates, which are more nuanced and difficult to determine. They also use CBR to estimate population changes and fluctuations in order to predict and prepare for shortages or surplus. Though not something we do in our spare time, calculating CBR is a simple, important process.
We look at the number of births in a given time period and population as the crude birth rate, or CBR. More specifically, CBR is the number of live births per year, is estimated mid-year , and is almost always reported per 1000 living people. Let's look at an example.
As the name implies, the CBR is a crude measure of public health. Crude measure in this sense doesn't mean awful or unmannerly; it actually refers to an unrefined or nonspecific way of figuring something out.
Population scientists use birth rates , including CBR, along with a lot of other factors to predict what the population of a country will be in 10 or 20 years. Even so, the CBR for a population does give some 'big picture' insight into what's going on in an area, region, or country.
Why do scientists even care about birth rates? The main reason that birth rates in general are calculated is so future populations can be predicted. Government officials living in a country with a population expected to double in 20 years would be facing a very different set of challenges than one where the population is expected to decline by 10%. Population scientists use birth rates, including CBR, along with a lot of other factors to predict what the population of a country will be in 10 or 20 years.
