### 1. What is large-scale data collection?

Certain data protection requirements only apply if your business collects data on a ‘large scale’.

Unlike the numerical thresholds set in some US data regulations, the [GDPR](/key-legislation/the-gdpr.md) does not set out a particular threshold for when processing becomes ‘large scale’. Rather, it is assessed based on several factors. These include: 

* the **number** of data subjects concerned (although no number is given);
* the **variety** of data; 
* the **duration** of the processing; and
*  the **geographical spread** of the processing.

Based on suggestions from regulators (such as the ICO) and what we see in practice, the following categories are **common** **examples** of large scale processing:

* hospitals;
* insurance companies;
* banks;
* AI infrastructure companies; and
* businesses tracking individuals’ real-time locations.

### 2. Requirements for large-scale data collection

1. **DPO:** If your business conducts ‘large scale’ sensitive data collection or ‘large scale’ regular and systematic monitoring of customers, it is required (under the GDPR) to engage a [DPO](/privacy-professionals-when-do-you-need-them/when-do-you-need-a-dpo.md).
2. **DPIA:** Separately, where your business is deemed to be engaging in high-risk data processing, it must complete a data protection impact assessment (DPIA) before that processing begins. A [DPO](/privacy-professionals-when-do-you-need-them/when-do-you-need-a-privacy-partner.md) will help your business determine if a DPIA is necessary in your individual case.
