Scottish prison population projections: October 2025

As shown in Figure 2 there have been substantial fluctuations in both the total and sentenced populations since 2020.

Figure 2. Prison population (total, remand and sentenced), between 26th March 2020 and 1st October 2025[1].

Total population

As can be seen in Figure 2, the prison population fluctuated within a range between 7,350 and 7,650 from September 2020 until late 2022. In 2023 and 2024, the population grew significantly, peaking at 8,361 on 14th May 2024.

The Emergency Release (ER)[2] of certain short-term prisoners led to 477 individuals being released early in June and July 2024. Following this, the population rose again, reaching 8,260 on 6th December[3]. Seasonal fluctuations continued into early 2025, before the population increased to reach 8,375 on 18th February.

In November 2024, the Scottish Government passed an Emergency Bill, resulting in eligible short-term prisoners being released at 40% of their sentence rather than 50%. The 311 individuals immediately impacted were released in tranches in February and March 2025[4]. This brought the population down to 8,170 on 21st March. It increased during the following months, standing at 8,363 on 1st October 2025.

Remand population

The remand population increased in early 2024, peaking at 2,360 on 14th May. The population then declined in the second half of 2024, reaching 2,124 on 1st January 2025. The highest remand population in 2025 so far was 2,289 on 25th March 2025. It has since decreased, standing at 2,096 on 1st October 2025.

Sentenced population

The sentenced population decreased slightly during 2022, from around 5,350 in January to approximately 5,250 in December. It generally increased throughout 2023 and early 2024 until it reached 6,056 on 21st June 2024[5].

Following the ER measures[6], the sentenced population fell to 5,691 on 20th July 2024, but rose again later in the year. It stood at 6,108 on 17th of February 2025, just prior to the implementation of the Prisoners (Early Release) Act 2025. The population then declined to 5,891 on 23rd March, before increasing again to 6,267 on 1st October 2025..

Remand Arrivals and Sentenced Departures

The prison population varies according to the volume and composition of the flows into and out of the remand and sentenced populations. Remand arrivals and sentenced departures are particularly important as they represent the main inflows and outflows, respectively, from the overall prison population.

Figure 3 shows monthly remand arrivals and sentenced departures from April 2020 to September 2025. The three-month period with the lowest remand arrivals – excluding December due to seasonal effects – was May to July 2025, with an average of around 730 remand arrivals per month.

Sentenced departures peaked in March 2025, partly due to the second and third tranches of early release under the new legislation.

Composition of the sentenced prison population

Figure 4 shows the sentenced prison population from March 2020 to October 2025, broken down by sentence length. All population groups tended to increase between 1st January 2023 and June 2024. The short-term prison population decreased due to ER measures in June and July 2024 and again due to the short-term prisoner early release in February and March 2025.

The population serving overall sentences of more than four years, as well as those serving Orders of Lifelong Restriction, have steadily increased over several years and now exceed pre-pandemic levels. In contrast, the population serving life sentences has gradually declined since 2020.

Drivers of growth in prison population since 2023

The growth in the total prison population since the beginning of 2023 has been driven by increases in both remand and sentenced arrivals. The remand population is influenced by the level of new cases registered and the number of cases concluded in Scottish Courts[8]. Elevated court throughput (i.e., case conclusions) can lead to increased flow into the sentenced population. The Scottish Courts and Tribunals Service (SCTS) regularly publishes data on case registrations and conclusions across all court types.

On 1 April 2023, some court recovery programme resources were reallocated from summary to solemn procedure. This resulted in the addition of two High Court and six Sheriff Solemn trial courts[9], but a reduction of ten Sheriff Summary trial courts.

Figures 5 to 10 present trends in registrations and conclusions in recent years for High Court, Sheriff Court Solemn and Sheriff Court Summary[10].

Figure 5 shows the number of High Court indictment registrations over the last decade from 2014/15 Q1[11] (covering April to June 2014) to 2025/26 Q1. The level of very serious criminal cases registered has increased such that the number of High Court indictments registered in 2025/26 Q1 (351) was 32% higher than during 2024/25 Q1 (265). In the latest SCTS criminal court modelling[12], it is assumed that the average High Court indictments per quarter in 2025/26 will be 381.  

Figure 5. High Court Indictments registered.

Figure 6 shows that High Court conclusions during 2025/26 Q1 (282) were around 18% higher than during 2024/25 Q1 (238).

Figure 6. High Court Indictments concluded.

Figure 7 shows that Sheriff Solemn Indictment registrations in 2025/26 Q1 (1,713) were around 7% lower than during 2024/25 Q1 (1,840).

Figure 8 shows that conclusions also declined slightly, by 4%, from 1,941 in 2024/25 Q1 to 1,866 in 2025/26 Q1.

Sheriff Solemn imprisonment disposals are likely to continue to be elevated compared to prior to the introduction of additional solemn courts in April 2023; for example, in 2024/25 there were 6,351 imprisonments – 8% more than the 5,859 recorded in the same period in 2022/23[13].

Figure 7. Sheriff Court Solemn Indictments registered.

Figure 8. Sheriff Court Solemn Indictments concluded.

Figure 9 shows that 14,419 complaints were registered in 2025/26 Q1 in Sheriff Summary Courts, a 12% decrease from 16,344 in 2024/25 Q1.

Figure 10 shows that Sheriff Court summary conclusions in 2025/26 Q1 were around 14% lower than during 2024/25 Q1.

Sheriff Summary imprisonment disposals were around 13% higher in 2024/25 (12,155) than in 2023/24 (10,745)[14]. Therefore, despite the reduction in Sheriff Summary courts from April 2023, the upward trend of imprisonment disposals – beginning in Q1 2022-23 – has continued, with levels now comparable to pre-pandemic levels.

Taking all courts into consideration, elevated remand arrivals are associated with increased levels of both summary and solemn criminal court activity[15].

SCTS quarterly management information shows that the total number of trials scheduled[16] across all criminal courts increased steeply by around 140% from 18,100 in April 2020 to over 43,600 at the peak in January 2022 due to the consequences of the COVID-19 pandemic. By the end of July 2025, this had fallen to 17,993[17] .

However, trends vary by court type:

• Figure 11 shows that the number of outstanding High Court trials has increased by 19% between June 2024 (688) and June 2025 (818).
• Figure 12 shows that outstanding Sheriff Solemn trials decreased by 37% over the same period, reflecting the impact of enhanced solemn court capacity.
• Figure 13 shows a substantial 30% reduction in outstanding Sheriff Summary trials between June 2024 and June 2025.

The management information in the disposals dashboard shows disposals issued in Scottish criminal courts at charge level. This data does not indicate how many people received disposals as each accused person can have multiple charges and each charge can receive multiple disposals. Therefore, a change in charge level disposals could be related to changes in complexity of cases being disposed of in court (more or less charges per case). As such, the level of imprisonment disposals provides a broadly indicative, rather than precise, measure of activity.
