Build data Website and accompanying App

Hi, I have an simple empirical formula that can be adopted to give results in any country where such data is available. IT WILL OFFER AN APPROXIMATE CALCULATION OF HOW MANY INDIVIDUALS ARE BELIEVED ALIVE THAT WERE BORN IN THE SAME COUNTRY AND HAVE THE IDENTICAL DATE AND YEAR OF BIRTH (I.E THEY WERE BORN ON THE SAME DAY AND YEAR IN THE SAME COUNTRY I want a user to be able to visit a SLEEK website and key in VERY SIMPLY their (1) Country of birth from a drop down country tab (2) Gender from a drop down tab (3) Full date of birth from a drop down tab (4) Email address and Name (5) Press the 'result' button For Example: John Martinez from Germany age 54 visits the site He keys in his details and the Results appear instantly with his National Flag etc appearing THE RESULTS will show for his particular country of birth. 1. How may individuals were born approximately on his birthday 2. How may males were born on his birthday 3 How many females were born on his birthday 4. How many males approximately believed alive today (i.e date of website visit) 5 How many females approximately believed alive as of today (i.e date of website visit) 6. A 'John Martinez' specific result .. (A)..' Hi John as of todays date there are 54 males believed alive in Germany born on January 4th 1964 (B) You may be expected to live until 2041 given the current life expectancy for males in Germany *The website and app will be pretty easy to build. * The only backend data needed from any country where the data is available is (1) records of the annual number of births by year (2) record of current life expectancy of males and females from that country **The simple empirical formula i have come up can be activated in the backend when the user inputs their simple data ***An extra add on would be A SOCIAL PLATFORM ( at the results section) where users have the option to post a comment and connect with other individuals etc etc on their results specific page that would only be seen by other users with the exact same date year and country of birth Thanks, Neil
