Not much there either, but I got numbers for total PhDs awarded in the UK in 2004 and 2005, also for those in Physical Science (no specific Chemistry item), and a gender breakdown. Small mercies etc...
2004:
All PhDs: Male: 8682 (57%) Female: 6575 (43%)
Physical Science: Male: 1503 (66%) Female: 777 (34%)
2005:
All PhDs: Male: 8949 (57%) Female: 6829 (43%)
Physical Science: Male: 1536 (66%) Female: 798 (34%)
Numbers vary, proportions remain the same.
Wales
Wales is home to 13 higher education institutions (HEIs) ranging in size from over 24,000 students at Cardiff University (around 70% full-time) to 7,000 at University of Wales, Lampeter (where a large majority are part-time students). Figures from HEFCW and NECTW for 2002/03 state that 5,085 students were enrolled on research degree programmes and that 605 doctorates were awarded
