WHAT IS DATA SCIENCE?

Data science is an interdisciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from structured and unstructured data, and apply knowledge and actionable insights from data across a broad range of application domains. Data science is related to data mining, machine learning and big data.

Data science is a “concept to unify statistics, data analysis, informatics, and their related methods” in order to “understand and analyze actual phenomena” with data. It uses techniques and theories drawn from many fields within the context of mathematics, statistics, computer science, information science, and domain knowledge. However, data science is different from computer science and information science. Turing Award winner Jim Gray imagined data science as a “fourth paradigm” of science (empirical, theoretical, computational, and now data-driven) and asserted that “everything about science is changing because of the impact of information technology” and the data deluge.

BENEFITS OF DATA STRUCTURE:

The organizational importance of Data Science is continuously increasing. According to one study, the global Data Science market is expected to grow to $115 billion by 2023. Some of the many Data Science benefits include the following:

  • In the healthcare industry, physicians use Data Science to analyze data from wearable trackers to ensure their patients’ well-being and make vital decisions. Data Science also enables hospital managers to reduce waiting time and enhance care.
  • Retailers use Data Science to enhance customer experience and retention.
  • Data Science is widely used in the banking and finance sectors for fraud detection and personalized financial advice.
  • Transportation providers use Data Science to enhance the transportation journeys of their customers. For instance, Transport for London maps customer journeys offering personalized transportation details, and manages unexpected circumstances using statistical data.
  • Construction companies use Data Science for better decision making by tracking activities, including average time for completing tasks, materials-based expenses, and more.
  • Data Science enables trapping and analyzing massive data from manufacturing processes, which has gone untapped so far.
  • With Data Science, one can analyze massive graphical data, temporal data, and geospatial data to draw insights. It also helps in seismic interpretation and reservoir characterization.
  • Data Science facilitates firms to leverage social media content to obtain real-time media content usage patterns. This enables the firms to create target audience-specific content, measure content performance, and recommend on-demand content.
  • Data Science helps study utility consumption in the energy and utility domain. This study allows for better control of utility use and enhanced consumer feedback.
  • Data Science applications in the public service field include health-related research, financial market analysis, fraud detection, energy exploration, environmental protection, and more.

GROWTH IN DATA SCIENCE:

If you’ve been following this article along, then you probably have a good assumption on the trajectory of the growth of data science jobs.

Per LinkedIn, there has been a 650% increase in data science jobs since 2012. Glassdoor gives evidence to this claim as they had about 1700 job postings with data science being the primary role in 2016. That number rose to 4500 in 2018, and sort of flattened out in 2020 at around 6500.

COVID-19 was the big story in 2020, and presumably, the reason for this flattening out. Overall though tech jobs have proven to be resilient during the pandemic, which is now in its tenth month.

WHEN DEMAND IS HIGH:

Demand for Data Scientists is still high while supply is low. According to IBM, this tendency will continue to be strong for years to come. Another credible source that agrees with this statement is the U.S. Bureau of Labor Statistics.

The U.S. Bureau of Labor Statistics sees strong growth in the data science field and predicts the number of jobs will increase by about 28% through 2026. To give that 28% a number, that is roughly 11.5 million new jobs in the field.

In the long term, it would probably be unwise to bet against data science as a career move, especially when you widen the field to include related positions like research engineers and machine learning engineers.
