## The Population of China vs. IsraelThe increase of the Chinese vs. Israely population over the years

For many years, China had the biggest population in the whole world. The population in the country is huge standing at 1,386,830,180 people! Even though in a couple years India may get to those numbers too, I'm pretty sure today it is the country with the biggest population in the whole world. Interesting fact, every 5-6 second, someone is born in Chinese or someone Chinese is born? One of the two I'm not sure. Which means that the number I wrote ain't accurate by now! Unlike Israel which was announced as a country only about 70 years ago and has a very small population, standing on 8,630,000 people or maybe more by now? Who knows?!

But more important, this is the growth of the Chinese and Israeli populations since 1955. It is just amusing how they grew!

Chinese Population vs. Israeli Population
Graph with Lines of Best Fit

Extra note; I'm pretty sure that at the time period of the third interval there was the law put about only one child being allowed for each family in China.

Slope A + B Caculations
Slope C Caculations
Final Slope Caculations

For the Chinese population, the slope for the first interval is y= 15.3 x + 600 and the slope for the second interval is y= 15.8 x + 600. The slope for the third interval is y= 6.95 + 950 and the for the line a best fit is y= 12.73 x + 600. For the Israeli population, the slope for the first interval is y= 0.085 x + 1 and the slope for the second interval is y= 0.11 x + 1. The slope for the third interval is y= 0.14 x + 1 and for all the line a best fit is y= 0.35 x +1.

Estimation of Populations Calculations for Years 2067 and 2112

Based on the final slope, I estimate that on 2067 the population of China will be about 2025.76 million people and on 2112 the population will be about 2598.61 million people. Very differently, the population of Israel on 2067 will be approximately 40.2 million people and 56 million people on 2112.

My graph just shows that there are more and more people even though a lot of people die. It doesn't make a lot of sense because there is a law that says that every family can have only 2 children and in Israel the average family doesn't usually have more than 3 children but still there is a big increasment of a couple millions a year in both countries.

I am assuming that my line a best fit for China is wrong since in the past few years laws about how many children are allowed in a family came out and the population growth went smaller. It affects my predictions since I based it mostly on the years before the laws came out. For Israel the line makes a tiny bit more sense but since the country isn't big 56 million people doesn't sound plesent to me...
