Population

Population data has Daytime_Population and Population_Density by area. Using these 2 variables, "Floating_Population" variable is created by taking Population_Density away from Daytime_Population.

Floating.png

"Floating_Population" represent how many people are moving into each area as well as moving out after work.

Box plot with area, population density, and floating population

It is straight forward that area Suburbia has the largest population followed by Lakeside and Riverside whereas area Uptown has the largest floating population followed by Downtown and Westside. Also, all of top 7 areas have negative floating population, meaning people are travelling to Uptown, Downtown and Westside everyday for work.


Weather

Wind speed and direction are presented below.

Heatmap of wind speed and direction

Wind direction has changed from South/East to North/West from May 4th. It gets very strong from May 3rd till May 8th, and get strong again from May 11th onward.


Key Words Analysis

Following key words are used for analysis.

Diagnosis flu, cold
Symptoms fever, chill, sweat, pain, fatigue, cough, breathing difficulty, nausea, vomit, diarrhea, headache, sick, shortness of breath, declining health, hurts to move, aching muscles, sore throat, runny nose, problems breathing, pneumonia

Using above key words, text traffic is plotted into Vastropolis map.

Date Flu Cold Symptoms
May 16th Flumap16.png Coldmap16.png Symmap16.png
May 17th Flumap17.png Coldmap17.png Symmap17.png
May 18th Flumap18.png Coldmap18.png Symmap18.png
May 19th Flumap19.png Coldmap19.png Symmap19.png
May 20th Flumap20.png Coldmap20.png Symmap20.png

Above series of plot in Map shows following points.

  • Frequency of text cold leap up on May 18th whereas frequency of text flu remain clam on same day. Cold is less likely used for diagnosis, but is likely used to describe temperature.
  • Frequency of text Symtom leap up on May 18th, then text flu leap up on following day. People describe their contagion symptoms 1 day before writing flu.
  • Frequency of text cold decreased on May 19th. It may referring the temperature of Vastropolis warm up again.
