AbstractDetailed twin birth rates for the United States are unavailable since 1964. In 1983 the crude twinning rate for women of white race was higher than in 1964, but there had been great changes in maternal age and parity. Indirect standardization for maternal age and birth order provides estimated total twinning rates that can be compared over the entire period. The adjusted rates for whites show a nearly continuous increase except after a 2-year reporting hiatus, 1969-70, when rates dropped back 10%. In blacks the adjusted rate increased between 1966 and 1978, except for the 1968-71 shift. The distributions of rate increases by maternal age and by race argue against effects of medical ovulation stimulants, but a disproportionate increase of triplets argues for such effects. Study is needed of rates specific for maternal age and parity, rather than of total rates.

American Economy

The American economy suffers from a general budget deficit, mainly due to the high public expenditures, especially the military, as the United States of America occupies the first place in the world in the proportion of military spending, and the budget deficit is mainly financed through the sale of government securities, which led to an increase in the volume of public debt In the United States of America, which is a dangerous indicator, especially after interest payments on public debt exceeded the barrier of $ 500 billion for the year 2018, which pushes them to borrow again to finance these benefits, this cumulative and continuous increase in the size of public debt works to influence the economic variables Monetary and financial. The research aims to analyze the development of internal public debt in the United States of America and its most important causes, in addition to clarifying the mechanisms and methods used to alleviate the severity of the internal public debt without compromising the ability of the economy or the ability to repay previous debts to maintain investor confidence in the strength of the American economy. The research reached several results, the most prominent of which is that the large increase in the volume of the internal public debt and the consequent increase in the money supply did not negatively affect the monetary side of the economy as inflation rates did not reach high levels and international reserves increased, accompanied by a decrease in interest rates. While the research presented several recommendations, including the need to achieve financial discipline and market access to borrow at the lowest possible costs by issuing debt regularly, in addition to avoiding resorting to any special measures to increase the volume of public debt and adhere to the debt ceiling approved by the US Congress.

The Impact

Objectives. To examine the differences in adolescent birth rates by deprivation and Health Professional Shortage Areas (HPSAs) in rural and urban counties of the United States in 2017 and 2018. Methods. We analyzed available data on birth rates for females aged 15 to 19 years in the United States using the restricted-use natality files from the National Center for Health Statistics, American Community Survey 5-year population estimates, and the Area Health Resources Files. Results. Rural counties had an additional 7.8 births per 1000 females aged 15 to 19 years (b = 7.84; 95% confidence interval [CI] = 7.13, 8.55) compared with urban counties. Counties with the highest deprivation had an additional 23.1 births per 1000 females aged 15 to 19 years (b = 23.12; 95% CI = 22.30, 23.93), compared with less deprived counties. Rural counties with whole shortage designation had an additional 8.3 births per 1000 females aged 15 to 19 years (b = 8.27; 95% CI = 6.86, 9.67) compared with their urban counterparts. Conclusions. Rural communities across deprivation and HPSA categories showed disproportionately high adolescent birth rates. Future research should examine the extent to which contraceptive access differs among deprived and HPSA-designated rural communities and the impact of policies that may create barriers for rural communities.
