Free Public Datasets for Your Data Science Project in 2025

Data science is all about finding interesting insights and stories from that data. And you can say data is crucial for data science. Your data science project is mostly dependent upon the goodness of the dataset. That’s why in this article I am gonna share Free Public Datasets for Your Data Science Project.

Thankfully there are various online data sources available where you can get free open source datasets for your project. You just need to download the datasets and use them for your project.

So without further ado, let’s get started-

Free Public Datasets for Your Data Science Project

1. Data.gov

Data.gov is the repository of the US government which you can use for your research and data science projects such as data visualization, mobile applications, etc. You can directly use some of the datasets without even registering on the site. But some datasets require licensing agreements before downloading the dataset. You can search for a specific data set or you can find datasets in the topic section-

2. Google Cloud Public Datasets

Google has a cloud hosting service named Google Cloud Platform. Where you can explore datasets by using a BigQuery tool. For obtaining better patterns and insights, you can create data visualizations and interactive dashboards by using Google Data Studio.

You just need to create an account on GCP for accessing the data. GitHub, United States Census Bureau, NASA, BitCoin, US Department of Transportation, etc are the data providers on GCP.

3. Kaggle

Kaggle is one of the famous platforms for data science, and you can download approx 68,000 public datasets on Kaggle free. In Kaggle you need to create an account and then you can search for any specific dataset in the search bar. You can also donate datasets on Kaggle and other community members can vote and run Kernel/scripts on them. 

In Kaggle, you can also take part in various competitions and can download the competition data sets from Kaggle.

4. UCI Machine Learning Repository

The UCI Repository has public datasets available for machine learning and data science. The best thing in UCI Repository is that datasets are tagged with different categories such as classification, regression, recommender system, etc.

These categories will make your findings easier. The datasets available on UCI are contributed by various people. So if you are a machine learning practitioner, then you should check the UCI Machine Learning Repository.

You don’t need to register on the site, you can directly download the datasets from the UCI Machine Learning repository.

5. AWS Public Data sets

Amazon has a huge amount of datasets available on their open data registry. You can easily download the datasets and use them for your project. You can also analyze the data on the Amazon Elastic Compute Cloud (Amazon EC2).

Full Enron email dataset, Google Books n-grams, NASA NEX datasets, Million Songs dataset are some of the popular datasets available on Amazon.

6. Quandl

Quandl is the best platform for financial, economic, and alternative data. Some of the datasets are free, but some require purchase. You can use Quandl datasets for stock price prediction or economic indicators prediction.

Stock Exchange data from India is freely available on Quandl. If you search properly, you will get some good free datasets.

7. The World Bank 

The World Bank is a global development organization and provides open datasets. In the World Bank, you will find several resources for datasets such as DataBank, Open Data Catalog, Microdata library, etc.

You can also find datasets by Regions and Countries-

8. Indian Government OpenDataset

data.gov.in is the website by the Government of India, where you can find free datasets from various industries such as climate, health care, transport, education, economy, etc.
