Big Data Analysis on Job Trends Using R



Nowadays, the demand for data science-related job positions have seen a
huge increase due to the recent data explosion incurred by the industries and organizations globally.
The necessity to harness and utilize the amount of information hidden inside these huge datasets for
effective decision-making has become the need of the hour. However, this scenario is where a data
analyst or a data scientist comes into play. They are domain experts who have the skillset and expertise
to extract hidden meaning from data and convert them into useful insights. This work illustrates
the use of data mining and advanced data analysis techniques such as data aggregation, summarization
along with data visualization using R tool to understand and analyse the job trends in the United
States of America (USA) and then drill down to analyse job trends for data science-related job positions
from year 2011 to 2016.



This paper discusses the general job trends in the US and how the job seekers are migrating
from one place to another place using Visa for different titles, majorly for business analytics.



 Analytics is done using R programming, different functions of the programming on various
parameters and inference is drawn on the result.



The aim of this analysis is to predict the job trends in line with demand, region,
employers, wages in USD.
