The World's "Youngest" Countries

-




With worldwide birth-rates declining and average human ages and life expectancies increasing, what are the world's youngest countries? Above is a visualization based on 2012 data on each country's population percentage that falls between 0-14 years old. The United States has 19.6% of the population between 0-14 years old. On the highest end of the spectrum are Central African countries like Niger, Chad, and Angola with 50%, 48.5% and 47.5% of their populations falling into the 0-14 year old category. Do less developed countries' populations have higher percentages of children? This visualization seems to suggest so. Specifically in Africa, is this phenomenon due to high birthrates, lower overall life expectancy, or both? Below, you can see the corresponding visual for each country's birthrate that same year.






These phenomenon seem inextricably and obviously linked. Higher birthrate means higher population of children. This visual seems to help prove that the two fields are related but not much else is gained here.  Finally, we can see the average life expectancy for each country below:





This information seems to support our previous thesis that a combination of high birthrate and low average life expectancy are behind the large percentage of children in these countries. What are the forward implications of these statistics? Growing and shrinking populations for Central Africa and the USA respectively? Time will certainly tell.

Using a Neural Network to Predict Pneumonia From X-Ray Images

-
Image
According to the American Lung Association , ' Pneumonia is an infection of the lungs that may be caused by bacteria, viruses, or fungi. The infection causes the lungs' air sacs (alveoli) to become inflamed and fill up with fluid or pus. That can make it hard for the oxygen you breathe in to get into your bloodstream. The symptoms of pneumonia can range from mild to severe, and include cough, fever, chills, and trouble breathing.' Pneumonia Infographic Patients with pneumonia could have the following symptoms: Cough that produces phlegm or sometimes blood Fever Shortness of breath or difficulty breathing Chills or shaking Fatigue Sweating Chest or muscle pain If a person is suspected of having pneumonia, a doctor will begin by asking the patient about their medical history and symptoms. Next will be a physical exam, so the doctor can listen to the patient's lungs. In checking for pneumonia, a doctor will listen for abnormal sounds like crackling, rumbling or wheezing. I

Using a Neural Network to Classify Lego Figures

-
Image
 The efficacy of image classification has grown leaps and bounds in recent years with the advent of neural networks. Without going into too much detail, an artificial neural network consists of a series of layers through which inputs flow becoming output predictions. Each layer is composed of a predetermined number of neurons, and each neuron feeds information to the next layer of neurons via weighted connections. These weights are real numbers that flow from layer to layer eventually reaching an output layer, producing a numerical prediction.  For the purposes of image classification, the inputs are pixels. These pixels are converted to numeric inputs by gray-scale figures or color codes (RBG, hex, etc). The output is the neural network's prediction of what that image contains. The neural network learns using a dataset of labeled images; recording correct predictions and attempting to grasp what elements of a picture correspond to which labels.  This abstract concept can be intui

Why are people leaving Illinois?

-
Image
  Illinois is famous for being one of the very few states in the country with negative population growth.   The goal of this analysis is to i dentify the key reasons for the declining population by extracting  meaningful insights   from unstructured text. The raw text used for this project is in the form of roughly 300,000 news articles and titles scraped from the web that reference Illinois, Chicago, or Springfield. This project was completed in Python & Pyspark with several Natural Language Processing packages.
