访问数组中的对象

Question

我已经从csv文件中创建了一个对象数组，所以：

var s=[];
d3.csv('income.csv', function(data) {
  data.forEach(function(d, i) {
    w={};
    w.geoID= data[i]['GEO.id2'];
    w.population = data[i]['HC01_EST_VC15'];
    s.push(w);
  })
})

console.log(s); 
console.log(s[1].geoID);

console.log（s）显示：

[]
0: Object { geoID: "Id2", population: "Households; Estimate; Mean income (dollars)" }
1: Object { geoID: "37001", population: "59084" }
2: Object { geoID: "37003", population: "52750" }
3: Object { geoID: "37005", population: "47715" }
4: Object { geoID: "37007", population: "45101" }
5: Object { geoID: "37009", population: "50702" }
6: Object { geoID: "37011", population: "56130" }

但是，console.log（s [1] .geoID）显示：

undefined

什么给出 - 我不仅仅是在这个名为's'的数组的索引1中调用geoID键吗？
