Love Data Week – February 10-14, 2025

Love Data Week is observed around Valentine’s Day each year. The actual date of Love Data Week often changes by year and is usually determined by a governing body, but this year, it takes place from February 10 to 14. However, the goal remains the same: celebrating data, and raising global awareness about the importance of data science and management. Stakeholders use the day as an opportunity to convene a community of data scientists and discuss contemporary issues affecting data management, sharing, privacy, preservation, reuse, and delivery.

History of Love Data Week

Data is everywhere and for everyone. Apart from the hype about Big Data and every other viral buzzword, data remains an integral part of digital technology and the basis for meaningful information. As humans become more digitally inclined, we generate larger volumes of data and create more resources for analytical study into behavioral patterns, useful for psychological research, scientific evaluation, and commercial purposes. With this insight, data scientists continuously strive to apply the best practices for managing data and analyzing it to discover distinct patterns and gain insights. Further, they work hard to retain data integrity, uphold its privacy, and keep it away from malicious actors.

Indiana University-Purdue University Indianapolis (I.U.P.U.I.) organized the maiden edition of Love Data Week in 2016 as a Valentine’s Day (week) program. To oversee the inaugural Love Data Week, a planning committee coordinated by Heather Coates, Librarian of I.U.P.U.I. Digital Scholarship and Data Management, was appointed. In 2017, the planning committee announced ‘Data Quality’ as the theme of Love Data Week for the year through its official website. In 2018, the theme was ‘Data Stories,’ and the theme for Love Data Week 2019 was ‘Data in Everyday Life.’

Beyond I.U.P.U.I., many institutions, academic libraries, research centers, and universities around the world also participate in Love Data Week — sometimes with their own data-related themes. Lectures, workshops, seminars, virtual events, and data-themed competitions are organized as part of the annual event. Speakers and participants are often invited from across the globe. Even when events vary, the goal remains to raise awareness — notably through social media campaigns — about data and build a worldwide community of data science enthusiasts, scientists, researchers, and librarians.

A Colossal Invention

The U.K. creates Colossus Mark 1 — widely regarded as the world’s first programmable electronic computer — specifically to analyze large volumes of data and decrypt Nazi codes during WWII.

Tukey Predicts the Future

John W. Tukey publishes his famous article “The Future of Data Analysis” in The Annals of Mathematical Statistics, questioning the relationship between statistics and data analysis.

I.A.S.C. is Formed

The International Association for Statistical Computing (I.A.S.C.) is founded with the mission “…to convert data into information and knowledge.”

Apache Hadoop is Born

Computer scientists Mike Cafarella and Doug Cutting launch Apache Hadoop, an open-source framework for storing and analyzing vast volumes of data.

A New Buzzword

Computer scientists D.J. Patil and Jeff Hammerbacher describe themselves as ‘data scientists.’

Love Data Week FAQs

Is Python mandatory for data scientists?

Although most data scientists recommend proficiency in Python for a successful career, it’s not mandatory. Other valuable languages for data science other than Python include R, JavaScript, Java, C/C++, and C#. Knowledge of SQL is also a great asset.

Are data scientists happy with their jobs?

Apart from an estimated salary ranging from $65,000/year to $153,000/year that data science engineers earn, studies have revealed that most data scientists actually enjoy their job. According to a survey, about 90% of data scientists surveyed opined that they are happy with their job, and 50% admitted that they are thrilled to be data science engineers.

What are the six V's of Big Data?

In 2001, Doug Laney listed the 3V’s (dimensions and properties) of Big Data as Volume, Variety, and Velocity. The other V’s — veracity, value, and variability — were added over time.

  1. More text data than anything else

    91% of the data used in data science and analytics is composed of text data.

  2. More time on data cleaning

    According to an I.B.M. study, data scientists actually spend 20% of their time on data analysis, and 80% of their time performing data searches, organization, and cleaning.

  3. Data scientists prefer Python

    About 75% of data scientists use Python programming language because of its accessibility, simple syntax, and flexibility.

  4. Only tiny bits of data are analyzed

    Only about 0.5% of all forms of data we create are ever analyzed and used.

  5. Loss due to low-grade data

    Low-grade data costs organizations worldwide about a loss of 15 million dollars each year, with U.S. businesses alone losing $600 billion every year due to poor data quality.
