Is there a way I can shorten the below query into a single query?

I have the below query. IS there a way I can put this into one single query? If not, can I shrink it further anyway? Please advice.

 DECLARE @highRegion TABLE(regionId INT, countR INT)
    DECLARE @lowRegion TABLE(regionId INT, countR INT)
    DECLARE @midRegion TABLE(regionId INT, countR INT)

    INSERT INTO @highRegion
    SELECT c.fRegionID,
           COUNT(1) AS VALUE
    FROM   census.Country c
           INNER JOIN census.IncomeGroup ig
                ON  c.fIncomeGroupID = ig.IncomeGroupID
    WHERE  ig.Name IN ('High income: nonOECD', 'High income: OECD')
    GROUP BY
           c.fRegionID

    INSERT INTO @lowRegion
    SELECT c.fRegionID AS VALUE,
           COUNT(1)
    FROM   census.Country c
           INNER JOIN census.IncomeGroup ig
                ON  c.fIncomeGroupID = ig.IncomeGroupID
    WHERE  ig.Name = 'Upper middle income'
    GROUP BY
           c.fRegionID

    INSERT INTO @midRegion
    SELECT c.fRegionID,
           COUNT(1) AS VALUE
    FROM   census.Country c
           INNER JOIN census.IncomeGroup ig
                ON  c.fIncomeGroupID = ig.IncomeGroupID
    WHERE  ig.Name IN ('Lower middle income', 'Low income')
    GROUP BY
           c.fRegionID

    SELECT r.Name,
           r.NoOfCountries,
           h.countR AS HIGH,
           l.countR AS LOW,
           m.countR AS mid
    FROM   census.Country c
           INNER JOIN @highRegion h
                ON  c.fRegionID = h.regionId
           INNER JOIN @lowRegion l
                ON c.fRegionID = l.regionId
           INNER JOIN @midRegion m
                ON c.fRegionID = m.regionId
           INNER JOIN census.Region r
                ON  c.fRegionID = r.RegionID
