A nationwide salary survey by Robert Half International shows which jobs will command higher salaries in 2012.

The placement firm polled its clients to determine whether white-collar workers can expect salary increases in 2012. Here’s what the respondents predicted for various fields:

• Overall, white-collar workers can expect an increase of 3.4%.
• Workers in the accounting and finance fields are predicted to get a salary increase of 3.5%. Especially in demand: financial analysts and business systems analysts who can target growth areas, and tax accountants who can help firms navigate what are expected to be ever-more-complex corporate tax laws.
• IT professionals will see an increase of 4.5%. Systems and networking engineers are in strong demand, particularly in the specialty of cloud computing. No surprise: Mobile-applications developers will be in high demand.
• The salaries for administrative professionals will see the same rise as overall white-collar workers — 3.4%. The growth fields: customer service and almost anything associated with health care administration.
