Thanks, Chair. If I could make a start, but I think Julie has some specific case examples and we'll follow up in writing, with your agreement, as well. So, today it's really important that we don't distract from the experience of looked-after young people, and what I want to say is that we're incredibly proud of our looked-after young people. If you think about the past two and a half years and how their systems have changed dramatically, we're also incredibly impressed by the work that our foster carers, adopters and special guardians have done in supporting those young people.
All of Wales's heads of children's services have put together a paper called 'Children's services pressures', in which we have outlined the additional challenges we're facing at the moment. Some of those include increasing demand. So, if I speak for my own local authority, Rhondda Cynon Taf, we've experienced a 42 per cent increase in demand over the last two years, and that has affected services across the board. So, we've had to invest in early help services and new types of early help services as new needs are emerging, particularly for smaller children who've been born during that pandemic period and haven't had the same opportunities as well.
Some of the other challenges are around workforce and staffing. Further work is under way to understand more of it, but as services have developed, so the availability of social workers—qualified and experienced social workers—for safeguarding, court work, has diminished. So, some of the local authorities in Wales are working with teams that experience 30 or 40 per cent vacancy rates, and the context of that increasing demand adds to the constraints.
We also know, given the world that young people are experiencing at the moment, that some of the young people we're meeting for the first time have come in with a level of complexity—so, I'm giving examples here of young people who children's services have not previously known, not families where we've had involvement over several years—coming straight in and having very high-end complex needs, where opportunities for prevention work, working to keep families together, working to keep all children safe with their relatives, are not available to us, due to the level of risks and complexity within that.
Some of the other challenges that we've faced, really, are having partner services available at the right time when we need them, and through regional partnership boards, local authorities are having discussions with CAMHS, with health boards, about how we need to make services available in an integrated way, so that these most vulnerable young people who will need services across a range of services, including mental health, education, special education, criminal justice services, can experience strength-based approaches and integrated approaches, and the Children's Commissioner for Wales has spoken very strongly on this through the 'no wrong door' approach, which we think to be very important.
