The global datasphere is expected to grow at a compound annual growth rate of approximately 27% through 2030, reaching around 718 zettabytes annually, according to International Data Corporation (IDC) figures cited in Seagate Technology’s annual report. Hard disk drive (HDD) shipments show the same pull: Seagate shipped 789 HDD exabytes in fiscal year 2026, up from 595 in fiscal year 2025. The big data statistics below cover data volume, infrastructure spending, power use, the platforms that store and analyze data, business adoption and the jobs market.
Spending and hiring are projected to rise with the data. Gartner forecasts data center systems spending of $822 billion in 2026, up from $506 billion in 2025, a rise of 62.5%, and the Bureau of Labor Statistics (BLS) projects employment of data scientists to grow 35% from 2025 to 2035. Every figure comes from a company filing or press release, a government data set, an energy agency report, an employer survey or a named forecast.

Data Center Electricity Use Statistics
- Data centers accounted for around 1.5% of the world’s electricity consumption in 2024, or 415 TWh, per the IEA’s Energy and AI report.
- Globally, data center electricity consumption has grown by around 12% per year since 2017, more than four times faster than the rate of total electricity consumption.
- Global investment in data centers has nearly doubled since 2022, according to the IEA.
- Data center electricity consumption is set to more than double to around 945 TWh by 2030, slightly more than Japan’s total electricity consumption today.
- The United States accounted for the largest share of global data center electricity consumption in 2024 (45%), followed by China (25%) and Europe (15%).
- In the United States, data centers account for nearly half of electricity demand growth between now and 2030.
View the data
Further out, the IEA Base Case sees global data center electricity consumption rising to around 1,200 TWh by 2035. The IEA describes uncertainty widening after 2030, so the 2035 figure is the least firm of the three.
Why it matters: AI is the most important driver of this growth, alongside growing demand for other digital services, according to the IEA. For anyone running big data workloads, that turns electricity supply into a planning constraint alongside storage hardware, because the same data centers host analytics, cloud storage and AI training.

What is a big data analytics salary?
Data scientists are the closest BLS occupation to a big data analyst role, so they serve as the measure here. The median annual wage for data scientists was $120,230 in May 2025, with database architects paid more and database administrators paid less, as the occupation chart above shows.
Big Data Job Growth Statistics
- Employment of data scientists is projected to grow 35% from 2025 to 2035, much faster than the average for all occupations.
- About 24,800 openings for data scientists are projected each year, on average, over the decade.
- Data scientists held about 275,600 jobs in 2025, with publishing, broadcasting, and content providers employing 12%.
- About 7,300 openings for database administrators and architects are projected each year, whose overall employment is projected to grow 4% from 2025 to 2035.
- Demand for machine learning skills shows up in the World Economic Forum’s Future of Jobs survey of executives: the three fastest-growing jobs in percentage terms are big data specialists, fintech engineers and AI and machine learning specialists.
View the data
Key finding: The World Economic Forum’s Future of Jobs Report 2025 surveyed more than 1,000 companies around the world, representing 22 industry clusters and more than 14 million workers, and 86% of respondents expected AI and information processing technologies to transform their business by 2030.
Is big data a good career?
Employment of data scientists is projected to grow 35% from 2025 to 2035, with about 24,800 openings projected each year, and the World Economic Forum lists big data specialists among the three fastest-growing jobs in percentage terms. Those projections favor analysis roles over database administration, though they describe demand, not any one person’s prospects.
Conclusion
The global datasphere is expected to grow at approximately 27% a year through 2030, reaching around 718 zettabytes annually, and the money and power behind it are projected to rise too: Gartner forecasts data center systems spending of $822 billion this year, and the IEA projects around 945 TWh of data center electricity by 2030. Company results from AWS, Snowflake, Databricks, MongoDB and Palantir show that demand is landing on the platforms that store, query and model that data.
For readers weighing a career, the clearest signal is the gap between roles: employment of data scientists is projected to grow 35% from 2025 to 2035, against 4% for database administrators and architects. The next Gartner forecast and the next round of quarterly results will show whether spending keeps pace with that growth.
