Tulsa, Oklahoma, USA: Correlations between Barometric Pressure and Child Birth Rates (1980-1995) – An Analysis Abstract It is a well-known fact that there are many societies and communities, some primitive and others quite modern, as well as individuals across the globe that firmly believe that the moon, through its periodic lunar cycles, influences fertility rates and conception. There is also prevalent across the globe some of those who believe that women conceive more when the barometer drops. While the lunar theory has been propagated through a large body of literature the other theory, the pressure one, has no written records.

It is also notable that the lunar theory has scientific proponents that believe that human biorhythms are linked to weather changes, a modern enough and accepted belief, and that weather changes, in turn, are influenced by lunar, solar and star cycles (Whole Earth Forecaster, Item 27, 2006). Nevertheless, the theory on the association of barometric pressure with human fertility is accepted as one that this paper deems worthwhile to investigate. The paper first undertakes a literature review that reveals that many climatic and weather variables such as temperature, precipitation, humidity and others affect, both adversely and beneficially, human physiology and psychology.

It also finds that fertility and birth rates are definitively associated with these climate and weather variables. There are also a number of factors associated with these variables that either enhance or diminish their effective strengths on humans. The paper includes these legitimate observations of reputed scientists. Nevertheless, the paper does not find any association between birth rates and fertility with barometric pressure in available literature. Thus, it is decided that it will conduct an individual study to find if barometric pressure can really be associated in any manner with birth rates and fertility.

The barometric pressure for Tulsa, Oklahoma, USA, for the period 1990-2000 is derived from the ‘National Oceanic and Atmospheric Association’ (NOAA) together with the number of births, the birth rates and the fertility rates for the same period from the ‘Oklahoma State Department of Health’. The birth rate is accepted as the most likely variable to check against the barometric pressure as it is detrended against population fluxes in the period under study.

The methodology decided upon is a simple Linear Correlation and Regression test at 5% significance level. This is so because there is no literature to support a view that there is at all any correlation between the atmospheric and human variables. It is decided that if any significant correlation does show in this test a more detailed test shall be conducted to study more intricate aspects of the relationship. The initial Pearson’s Correlation test shows that the values for (Coefficient of correlation) at. 326 do not specify any significant relationship between the atmospheric and human variables.

The (Coefficient of determination) value at. 106 reinforces this and the conclusion arrived at is definitely, there is no correlation between barometric pressure and human conception and birth rates. The. 95 confidence interval is also large for and this also signifies that any change in sample sizes will not significantly affect the correlationship results.
